Content-Type: text/html Potential HDTV Adopters Running head: POTENTIAL HDTV ADOPTERS A Profile of Potential High-Definition Television Adopters in the United States Michel Dupagne School of Communication University of Miami P.O. Box 248127 Coral Gables, FL 33124-2030 Phone: (305) 284-3500 Fax: (305) 284-3648 E-mail: [log in to unmask] Paper presented to the Media Management and Economics Division at the annual convention of the Association for Education in Journalism and Mass Communication, Chicago, IL July 1997 Abstract A telephone survey was conducted with 193 adults in a major U.S. metropolitan area to assess consumer predispositions toward high-definition television (HDTV) and profile potential adopters of this technology according to demographics, mass media use, ownership of home entertainment products, and importance of television attributes. Based on diffusion theory and communication technology adoption studies, this study hypothesized that male, younger, better educated, and higher-income respondents who are more frequently exposed to mass media channels and value television features more highly would be more aware of HDTV, express a greater interest in HDTV, and be more likely to purchase an HDTV set. Correlational analyses indicated that HDTV awareness was positively related to education, income, gender (male), newspaper use, ownership of home entertainment products, and picture sharpness; HDTV interest was negatively related to age and positively related to income, gender (male), moviegoing, ownership of home entertainment products, and picture sharpness; and HDTV purchase intention was positively related to screen size. Hierarchical regression analyses were also run to determine the relative importance of demographics, mass media use, ownership of home entertainment products, and television attributes in predicting HDTV awareness, interest, and purchase intention. A Profile of Potential High-Definition Television Adopters in the United States On April 3, 1997, after 11 long, and often contentious, years (see Brinkley, 1997), the Federal Communications Commission (FCC) concluded its proceedings on digital television (DTV). First, on December 24, 1996, the Commission adopted a standard for terrestrial DTV that will enable broadcasters to transmit programs in high-definition television (HDTV) or standard-definition television (SDTV) format (Federal Communications Commission [FCC], 1996). Digital HDTV will offer significantly better pictures than SDTV, which is essentially a digital version of the existing NTSC television system, because it will use the entire 6 Mhz bandwidth to deliver the signal. It will provide three main technical improvements over NTSC: (1) higher-picture resolution (1080 active lines versus NTSC's 525 scanning lines) approaching 35 mm picture quality; (2) a wider aspect ratio (16:9 versus NTSC's 4:3) approximating the movie theater experience; and (3) distortion-free multichannel audio (digital 5.1 channel system versus NTSC's analog stereophony) comparable to the sound quality of a compact disc (see Seel, 1996). Then on April 3, 1997, the Commission finalized the two remaining advanced television (ATV) rulemakings--general service rules and channel assignments. In the Fifth Report and Order, the Commission completely reshuffled the NTSC-to-HDTV transition schedule it had adopted in September 1992. It required that (1) the affiliates of ABC, CBS, Fox, and NBC in the top 10 markets (30% of TV households) build their DTV facilities by May 1999 and those in the top 30 markets (53% of TV households) by November 1999; (2) all remaining commercial stations construct their DTV facilities by May 2002; (3) all noncommercial stations construct their DTV facilities by May 2003; and (4) DTV licensees simulcast 50% of their analog video programming on the DTV channel by April 2003, 75% by April 2004, and 100% by April 2005. It also shortened the duration of the transition period from 15 to 10 years by setting the target date for the phase-out of NTSC service in 2006. More surprisingly, and contrary to previous actions, the FCC declined to mandate broadcasters to air a minimum amount of HDTV programming and, instead, left this decision to the discretion of the licensees (FCC, 1997a). In the Sixth Report and Order, the FCC adopted a Table of Allotments for digital television based on use of channels 2-51. Responding to comments, it added channels 2-6 to channels 7-51, which was originally proposed as the DTV core spectrum in the Sixth Further Notice of Proposed Rule Making of July 1996, to determine DTV channel assignments. Upon acceptability of the lower VHF channels 2-6 for DTV use, the Commission might ultimately shift the core spectrum from channels 7-51 to channels 2-46. According to the Table, over 93% of broadcasters would receive a DTV allotment that reaches at least 95% of their existing NTSC service area (FCC, 1997b). With the completion of these proceedings, the HDTV debate is now shifting in earnest from technology standardization and spectrum allocation to economic considerations, primarily programming and station conversion. Since the early 1990s, some U.S. broadcasters have expressed concerns, if not outright anger, at the cost of converting their facilities from NTSC to HDTV, especially within the FCC-prescribed transition window. Vocal comments, such as "HDTV will bankrupt stations" (McConnell, 1995, p. 103), were not uncommon a few years ago, though now many broadcasters have resigned themselves to accept the inevitability of HDTV by political and competitive necessity. On February 2, 1997, NBC, in cooperation with its owned-and-operated WRC-TV, became the first U.S. broadcast television network to transmit live a program (Meet the Press) in HDTV format. As of June 1997, seven stations were broadcasting experimental HDTV programs: WRAL-HD, Raleigh, NC; WRC-HD, Washington, DC; KOMO-HD, Seattle, WA; and KCTS-HD, Seattle, WA; KOPB-HD, Portland, OR; WETA-HD, Washington, DC; WCBS-HD, New York, NY. Conversion costs will depend heavily on station size and are difficult to estimate, but are likely to range from $1 million or less for pass-through equipment (i.e., to retransmit the network signal) to $10 million or more for complete local production facilities (McConnell, 1997). Surprisingly, amidst all these preparations, one key factor remains overlooked: the consumer (or demand) side. First HDTV sets are slated to hit the stores by Christmas 1998 at a price ranging from $5,000 to $11,000 (Dickson, 1997; "Zenith's First Digital Sets," 1997). Broadcasters and consumer electronics manufacturers have high expectations, but are American consumers ready for HDTV? How will they react to it? How aware of and interested are they in HDTV receivers? How will price influence the adoption of HDTV receivers and associated hardware? Early U.S. empirical studies, conducted in the late 1980s and reviewed below, reveal lukewarm consumer reactions to HDTV instead of unreserved responses that one would normally expect from a product that has been heralded as revolutionary and unique. The purpose of this paper is to revisit the consumer issue by assessing HDTV awareness, interest, and purchase intention in a major U.S. metropolitan area and identifying the characteristics of potential HDTV adopters based on demographics, mass media use, ownership of home entertainment products, and the importance of television attributes. Because previous studies were undertaken in the late 1980s, and now that HDTV is just around the corner, it seems particularly timely to reassess U.S. consumers' predispositions toward the technology. This study also offers theoretical insights, because, unlike past research, it is grounded in the diffusion of innovations literature. We would expect potential HDTV adopters to exhibit characteristics similar to those of earlier product adopters. Furthermore, it advances our understanding of diffusion theory by investigating the relative importance of demographics, mass media use, ownership of home entertainment products, and television attributes in explaining pre-adoption of a communication technology. Before detailing the hypotheses and the methodology, the paper will review three early HDTV consumer studies and summarize the main elements of diffusion theory. Early HDTV Consumer Studies in the United States Overall early consumer studies point to somewhat lukewarm predispositions toward HDTV and its technical improvements. John Abel, former Executive Vice President of the National Association of Broadcasters, went so far as declaring to a group of broadcasters that "You don't want HDTV. And consumers say they don't want it, either" (Andrews & Brinkley, 1995, p. 6). But in fact, consumer reactions are far from being negative except in the Home Box Office study. Neuman (1988) found that, when exposed to NTSC and HDTV material side by side (dual stimulus test), 62% of the participants preferred HDTV. With the exception of age, viewers did not differ on the basis of demographics, television use, or evaluations of picture characteristics (color, screen shape, picture sharpness, picture brightness, sense of depth, and motion quality). The author also reported that only 6% of the subjects assigned to the HDTV condition (single stimulus test) were willing to pay $500 on top of the price of their current television set for an HDTV receiver. Another study, conducted in Seattle, Washington, suggests more enthusiastic viewer responses to HDTV (Lupker, Allen, & Hearty, 1988). In side-by-side viewing, in which programming material was displayed alternatively, 73% of the respondents reported that HDTV was better than NTSC in overall picture quality. Respondents also preferred the HDTV set in terms of sense of depth (78%), screen shape (74%), picture sharpness (72%), color quality (69%), picture brightness (60%), and motion quality (57%). Of the respondents, only 14% and 18% indicated that they definitely or probably would buy an HDTV set like the one they were shown for $2,500 and $1,500, respectively. Home Box Office (1988) conducted the third study in Danbury, Connecticut, and found that only 39% of the respondents felt that HDTV was better than NTSC in overall picture quality. Respondents' preference for HDTV was also low in regard to screen shape (46%), color quality (43%), sense of depth (43%), picture sharpness (41%), picture brightness (41%), and motion quality (36%). But 17% and 23% of the respondents reported they definitely or probably would buy an HDTV set like the one they were shown within the next two years if available at $2,500 and $1,500, respectively. Diffusion Theory Rogers (1995) defines "diffusion" as "the process by which an innovation is communicated through certain channels over time among the members of a social system [emphases added]" (p. 5). The first element of this definition presupposes the existence of an innovation, which refers to an idea that is perceived as new by an individual. People evaluate an innovation in terms of six main attributes: relative advantage, compatibility, complexity, trialability, observability, and perceived risk. The sixth construct is not part of Rogers' set of perceived innovation attributes and was originally conceptualized by Raymond Bauer (see Ostlund, 1974). Rogers (1995) reports that his five attributes explain 49-87% of the variance in rate of adoption. Consistent with previous research, Holak and Lehmann (1990) found that compatibility (.558) and relative advantage (.455) were the perceived innovation characteristics most highly correlated with purchase intention of entertainment items (e.g., consumer electronics products), followed by perceived risk (-.160), communicability (i.e., observability) (.158), complexity (-.046), and divisibility (i.e., trialability) (.037). So the two most relevant perceived innovation attributes for communication technologies appear to be compatibility, the degree of congruence with potential adopters' values and needs, and relative advantage, the degree to which an innovative product is perceived to be superior to previous ones (see also Holak, 1988; Lin, 1996). Communication channels, the second element of diffusion, involves both interpersonal (e.g., word of mouth) and mass media (e.g., television) channels. While mass media channels offer the most effective means to create awareness and knowledge, that is, to inform the widest possible audience of individuals about the existence of an innovation, interpersonal channels are best to persuade potential adopters about the merits of an innovation. The third element is time, which is an important dimension in determining the innovation-decision process and measuring adopters' degree of innovativeness. The innovation-decision process is "the process through which an individual (or other decision-making unit) passes from first knowledge of an innovation to forming an attitude toward the innovation, to a decision to adopt or reject, to implementation and use of the new idea, and to confirmation of this decision" (p. 20). Therefore, it contains five main steps: knowledge, persuasion, decision, implementation, and confirmation. At the knowledge stage, the individual becomes aware of and gains basic information about the innovation (e.g., how does it work). Socioeconomic qualities, personality traits, and communication behavior can affect the degree of awareness and knowledge of an innovation. Specifically, earlier knowers are more likely to have more formal education, higher socioeconomic status, and greater exposure to mass media channels than later kwowers (Rogers, 1995). At the persuasion stage, individuals form favorable or unfavorable attitudes toward the innovation. They seek further information about the new idea and evaluate its pros and cons, relying particularly on interpersonal communication. In so doing, potential adopters develop a general perceptual map of the innovation primarily based on its relative advantage, compatibility, and complexity. At the decision stage, the individual "engages in activities that lead to a choice to adopt or reject an innovation" (p. 171). Individuals express their intention to adopt or reject the innovation (e.g., purchase intention and willingness to pay). On repeated occasions, marketing researchers have used purchase intention as a surrogate measure of innovation adoption, because they have found that purchase intention correlates with product trial (see Holak, 1988). The other two stages, implementation and confirmation, do not apply to this study, because HDTV sets were not yet available on the consumer market at the time of the survey. So this research investigates pre-adoption or potential adoption instead of actual adoption of HDTV. Rogers (1995) defines "adoption" as "a decision to make full use of an innovation as the best course of action available" (p. 171). He classified adopters into five groups according to their level of innovativeness: innovators (2.5% of adopters), early adopters (13.5%), early majority (34%), late majority (34%), and laggards (16%). Innovativeness indicates how soon an individual decides to adopt a new idea. Earlier adopters (innovators, early adopters, early majority) differ from later adopters (late majority, laggards) in socioeconomic status, personality values, and communication behavior. Specifically, they are better educated, have higher income, and use mass media channels more frequently than later adopters (Rogers, 1995). The fourth and final element of diffusion is the social system, which is "a set of interrelated units that are engaged in joint problem-solving to accomplish a common goal" (p. 23). Members of a social system can be individuals, groups, or organizations. Hypotheses Four sets of hypotheses were formulated based on diffusion theory and adoption studies for eight communication technologies (cable television, the video cassette recorder [VCR], the home satellite dish [TVRO], the personal computer [PC], videotex, audiotext, direct broadcast satellite [DBS], and the fax machine (see Table 1). A research question regarding the relative importance of these sets of variables in predicting HDTV awareness, interest, and purchase intention was also posed. The first four hypotheses relate demographic variables to the three dependent variables. H1.1: The younger respondents are, the more they will be aware of HDTV, express an interest in HDTV, and be likely to purchase an HDTV set. H1.2: The better educated respondents are, the more they will be aware of HDTV, express an interest in HDTV, and be likely to purchase an HDTV set. H1.3: The higher the income level of respondents is, the more they will be aware of HDTV, express an interest in HDTV, and be likely to purchase an HDTV set. H1.4: Male respondents will be as likely as female respondents to be aware of HDTV, express an interest in HDTV, and be likely to purchase an HDTV set. Rogers (1995) hypothesizes that "Earlier adopters are not different from later adopters in age" (p. 269), although he is quick to point out the conflicting empirical evidence about the relationship between age and innovativeness. In a majority of communication technology studies (Table 1; see also Lupker et al., 1988), age was found to be negatively related to adoption. Therefore, Hypothesis 1.1 posits a negative relationship between age and the three dependent variables. Consistent with diffusion theory and most adoption studies, we expected a positive relationship between level of education and income and HDTV awareness, interest, and purchase intention. Diffusion theory is silent on the relationship between gender and innovativeness (or adoption), but most empirical studies suggest that gender is unrelated to communication technology adoption. Consequently, it was hypothesized that there would no difference between males and females in HDTV awareness, interest, and purchase intention. The next block of four hypotheses deals with mass media exposure: H2.1: The more television respondents watch, the more they will be aware of HDTV, express an interest in HDTV, and be likely to purchase an HDTV set. H2.2: The more radio respondents listen to, the more they will be aware of HDTV, express an interest in HDTV, and be likely to purchase an HDTV set. H2.3: The more respondents read newspapers, the more they will be aware of HDTV, express an interest in HDTV, and be likely to purchase an HDTV set. H2.4: The more respondents see movies in theaters, the more they will be aware of HDTV, express an interest in HDTV, and be likely to purchase an HDTV set. Diffusion theory holds that earlier adopters will use mass media more frequently than later adopters (Rogers 1995), but that generalization is rarely borne out by empirical evidence for communication technology adopters (see Table 1). Amount of television viewing is the only significant media use predictor common to several adoption studies. More often than not, mass media use is unrelated to adoption of any of these eight communication technologies. Nevertheless, being theoretically grounded, this study hypothesizes that television use, radio use, newspaper use, and frequency of moviegoing will all be positively correlated with HDTV awareness, interest, and purchase intention. The third main hypothesis is a corollary of Hypothesis 1.3: H3: The greater the number of home entertainment products respondents own, the more they will be aware of HDTV, express an interest in HDTV, and be likely to purchase an HDTV set. Because earlier adopters generally have higher socioeconomic status than later adopters (Rogers, 1995), it follows that they will also be more likely to own consumer electronics items. Empirical research has shown that home satellite dish (TVRO), cable television, and personal computer adopters were more likely to own related entertainment products (e.g., video games, VCR, PC) than nonadopters (Danko & MacLachlan, 1983; Dickerson & Gentry, 1983; Lin, 1996; Litman, Chan-Olmsted, & Thomas, 1991; Rothe, Harvey, & Michael, 1983; see also Lupker et al., 1988). Therefore, we hypothesize a positive relationship between ownership of home entertainment products and HDTV awareness, interest, and purchase intention. The last group of hypotheses examines consumer responses to television technology attributes: H4.1: The higher respondents value the importance of picture sharpness, the more they will be aware of HDTV, express an interest in HDTV, and be likely to purchase an HDTV set. H4.2: The higher respondents value the importance of sound quality, the more they will be aware of HDTV, express an interest in HDTV, and be likely to purchase an HDTV set. H4.3: The higher respondents value the importance of screen size, the more they will be aware of HDTV, express an interest in HDTV, and be likely to purchase an HDTV set. These three television characteristics have often been touted as selling points for HDTV technology. Lupker et al. (1988) reported that motion quality, sense of depth, picture sharpness, and set size were all significant predictors of HDTV purchase intent at $1,500. At the $2,500 price range, significant predictors included motion quality and set size. Therefore, we would expect that the more respondents value picture sharpness, sound quality, and screen size, the more they will be aware of HDTV, express an interest in HDTV, and be likely to purchase an HDTV set. Finally, the following research question was posed: RQ: What is the relative influence of demographics, mass media use, ownership of home entertainment products, and television attributes in predicting HDTV awareness, interest, and purchase intention? Despite the voluminous diffusion literature, little research has been conducted to determine how blocks of variables such as those above compare to each other in predicting adoption of communication technologies. For instance, are demographics better predictors of adoption than mass media exposure, or is it the opposite? Jeffres and Atkin (1996) found that "assessment of media quality" and "media exposure" influenced people's likelihood to use new technologies for consumer purposes to a greater extent than did "demographics." Although a formal prediction is difficult to state at this point, we would expect, based on a number of empirical studies (see Danko & MacLachlan, 1983; Dickerson & Gentry, 1983; Litman, Chan-Olmsted, & Thomas, 1991; Lupker et al., 1988; Rothe, Harvey, & Michael, 1983), that both demographics and ownership of home entertainment products will play a significant role in determining HDTV awareness, interest, and purchase intention. Method A simple random sample of 613 phone numbers in the Miami, Florida, area were called during the evening hours of March 3 to March 20, 1995. Telephone numbers were drawn from the most recent edition of the city telephone directory, by first selecting randomly a page, then selecting randomly a column within the page, and finally selecting randomly a name with a phone number within the column. The last digit of the suffixes was then increased by 1 to account for unlisted phone subscribers. Interviewers were trained undergraduate students enrolled in a research methods class. All calls were made from a central location. Excluding non-eligible respondents (e.g., younger than 18), non-working numbers, and numbers that were never answered after six attempts, the completion rate was 58% (N = 193). The questionnaire contained questions about five topics: (1) importance of television attributes; (2) HDTV awareness, interest, and purchase intention; (3) ownership of home entertainment products; (4) mass media use; and (5) demographics. Television Attributes. Respondents were asked to rate the importance of picture sharpness, sound quality, and screen size on a 5-point scale ranging from extremely important (1) to not important at all (5). HDTV Awareness, Interest, and Purchase Intention. Next, they were asked to report their HDTV awareness ("Have you ever heard about high-definition television?"). Then, whether or not respondents were aware of HDTV, interviewers briefly explained the three main characteristics of HDTV technology (sharper pictures; high-fidelity sound; and larger and wider screen). Afterwards, they asked respondents to evaluate their degree of interest in HDTV ("In keeping these characteristics in mind, can you tell me how interested you would be in acquiring a high-definition television set"?) on a 4-point scale from very interested (1) to not interested at all (4). The third dependent variable dealt with purchase intention. The question was: "According to the manufacturers, a high-definition television set will cost about $3,000 when first introduced. Suppose that you decide to buy a new television set in 1995. How likely would it be that you would buy a high-definition television set at this price." The response set ranged from very likely (1) to not likely at all (4). Ownership of Home Entertainment Products. Respondents were asked whether they subscribed to cable television, and owned a VCR, a satellite dish, a video games system, a compact disc player, and a personal computer at home. These six variables were categorical (1 = yes; 2 = no). Mass Media Use. Fourth, respondents were asked about their television use ("On average, about how many hours a day do you watch television?"), radio use ("On average, about how many hours a day do you listen to radio?"), newspaper use ("How many days a week, if any, do you read a daily newspaper?"), and frequency of moviegoing ("How many times did you go to see a movie last month?"). In addition, respondents answered how often they watch wildlife documentaries and sports on television on a 5-point scale, from about every day (1) to never (5). Demographics. The questionnaire concluded with four demographic questions: age, education, income, and gender. Because the calling area was bilingual, two versions of the same questionnaire, one in English and one in Spanish, were prepared. Bivariate correlation analysis was used to test all hypotheses except the relationship between HDTV awareness and gender (chi-square test). Linear hierarchical regression was used to determine the relative influence of demographics, mass media use, ownership of home entertainment products, and television attributes in predicting HDTV interest and purchase intention. Logistic hierarchical regression, instead of linear regression, was used to answer the awareness component of the research question, because HDTV awareness was a categorical variable (see Hosmer & Lemeshow, 1989). All categorical variables were recoded as dummy variables (0 = no; 1 =yes). Scales for television attributes, viewing of documentaries, and viewing of sports were recoded from 1-5 to 5-1; scales for HDTV interest and purchase intention were recoded from 1-4 to 4-1. To test Hypothesis 3, an index for home entertainment products was created by aggregating responses to the six ownership variables (cable subscription, VCR, satellite dish, video games system, compact disc player, and personal computer). The scale ranged from 0 to 6. In the regression analyses, two specific viewing measures, sports and documentaries viewing, were added as predictors. There has been some speculation whether sports and wildlife documentaries might represent programming killer applications for HDTV, because these types of television content might greatly benefit from a wider aspect ratio (see Neuman, 1988). The inclusion of these variables in the media use block of the hierarchical regressions will allow us to explore this possibility. Findings Descriptive results The sample had a median age category of 30-39 and a median annual household income category of $30,000-$45,000. Of all respondents, 16.0% did not complete high school, 18.8% were high school graduates, 29.8% had some college, 20.4% were college graduates, and 14.9% pursued graduate work or received a graduate degree. In all, 65.1% had at least some college education. Females comprised 50.8% of the sample. Nationally, the median age was 34, the median annual household income was $32,264 (1994), 51.2% of the population were female, and 47.7% had at least some college education (U.S. Bureau of Census, 1996). So the composition of the sample did not differ demographically from that of the national population except in educational level. Respondents' ownership of home entertainment products also reflected national trends (see Consumer Electronics Manufacturers Association, 1996; National Cable Television Association, 1995). Of the respondents, 67.7% subscribed to cable television, 84.6% owned a VCR, 10.1% owned a satellite dish, 41.8% owned a video games system, 62.4% owned a compact disc player, and 38.3% owned a personal computer. Nationally in 1995, 64% of all U.S. households subscribed to cable television, 88% owned a VCR, 63% owned a compact disc player, and 40% owned a personal computer. An overwhelming majority of respondents rated sound quality (82%) and picture sharpness (77.8%) as either "very important" or "extremely important." But only 45% felt that screen size was either "very important" or "extremely important." On average, respondents watched about 3 hours and 4 minutes a day, listened to radio for 2 hours and 47 minutes, read a daily newspaper four times a week, and attended movies 1.67 times during the month preceding the survey. In addition, 46.2% and 37.1% watched wildlife documentaries and sports programs at least a few times a week, respectively. The study also revealed that 32.1% of the respondents were aware of HDTV. A majority (58.3%) expressed interest in acquiring an HDTV set based on the specifications enunciated by the interviewers (somewhat interested: 25.3%; very interested: 33%). On the other hand, only 15.5% indicated that they would be likely to purchase an HDTV receiver at a price tag of $3,000 (somewhat likely: 9.6%; very likely: 5.9%). Hypotheses None of the hypotheses received full support for all three dependent variables--HDTV awareness, interest, and purchase intention (Table 2). However, both Hypothesis 1.3 (income) and Hypothesis 4.1 (picture sharpness) came close by correlating significantly with both HDTV awareness and interest. Higher-income respondents and those who placed more importance on picture sharpness were more aware of HDTV and expressed a greater interest in an HDTV set than lower-income respondents and those who felt that picture sharpness was less important. As expected, age was negatively related to HDTV interest (H1.1); education was positively related to HDTV awareness (H1.2); newspaper use was positively related to HDTV awareness (H2.3); frequency of moviegoing was positively related to HDTV interest (H2.4); and screen size was positively related to HDTV purchase intention (H4.3). Contrary to Hypothesis 1.4, gender was significantly related to HDTV awareness (X2[1, N = 181] = 14.69, p < .001): Male respondents were more aware of HDTV than their female counterparts. Males also expressed a greater interest in an HDTV set than females, although that correlation coefficient (r = .14) was marginally significant (p = .060). Finally, Hypothesis 3 (home entertainment products) was supported for HDTV interest and marginally so for HDTV awareness (p = .069). Those respondents who owned more home entertainment products were more interested in HDTV than those who owned fewer of these items (Table 2). Research Question The research question examined the relative influence of demographics, mass media use, ownership of home entertainment products, and television attributes in predicting HDTV awareness, interest, and purchase intention. Demographic variables (age, education, income, and gender) were entered first, followed by mass media use (television use, radio use, newspaper use, moviegoing, documentaries viewing, and sports viewing), ownership of home entertainment products, and importance of television attributes (picture sharpness, sound quality, and screen size). The logistic hierarchical regression reveals that income, gender (male), and picture sharpness were significant positive predictors of HDTV awareness (Table 3). The Wald statistic, the equivalent of the t test in linear regression, was used to determine the statistical significance of the regression coefficients (see Norusis, 1994). The improvement chi-square (X2) test, which is comparable to an F-change test in linear regression, tested the null hypothesis that coefficients for the variables added at each step of the regression were 0. The findings indicated that the model with the demographic variables (block 1) constituted a significant improvement in predicting HDTV awareness over the constant-only model. Importance of television attributes (block 4) contributed significantly (p = .078) to improving the fit of the HDTV awareness model. In the first linear hierarchical regression (Table 4), age (negative), income, moviegoing, sports viewing (p = .064), and picture sharpness (p = .088) were found to be significant predictors of HDTV interest. Independent variables accounted for 25% of the variance in interest in acquiring an HDTV set. Television attribute variables were more successful than mass media use and ownership of entertainment products in explaining additional variance in HDTV interest above that for the first block. In the second linear hierarchical regression (Table 5), the only major predictor of HDTV purchase intention was screen size. Independent variables accounted for 11% of the variance in the HDTV purchase intention model. Only the R2 change for the block containing television attributes was significant. Discussion and Conclusions While some hypotheses did not gain support, especially in regard to HDTV purchase intention, those who did were almost always consistent with diffusion theory and research. Although it is difficult to profile HDTV potential adopters with great precision because the technology is still in a pre-adoption stage, certain characteristics clearly emerge. Innovators and early adopters of HDTV receivers will likely have higher income, be frequent moviegoers, watch sports programs, and express a keen interest in large-screen televisions. This preliminary description is consistent with past research conducted outside and in the United States. For instance, Bouwman, Hammersam, and Peeters (1993) also found that those Dutch respondents who desired a wider and larger screen as a television improvement were more willing to buy an HDTV set for about ECU 2,200 (about $2,700). In their Belgian study, Dupagne and Agostino (1991) reported positive correlations between moviegoing and importance of having an HDTV set at home. The finding that sports viewing is a predictor of HDTV interest substantiates some anecdotal evidence that content will matter in the adoption of HDTV (see Neuman, 1988). It may well be that sports programming aired in HDTV could produce highly favorable attitudes among potential viewers, which could in turn increase existing viewership. Though insignificant in the regression analysis, there was a significant positive relationship between the number of home entertainment products owned and HDTV interest. Again, this result confirms previous HDTV audience research (see Lupker et al., 1988). The hierarchical regressions revealed that demographics and television attributes were stronger predictors of HDTV awareness and interest than mass media use and ownership of home entertainment products. Jeffres and Atkin (1996) noted "a diminished role for demographics" (p. 328) in their study of technology use, but that observation was not supported in this study. Future diffusion research should evaluate whether the influence of demographics on communication technology adoption depends on the nature or characteristics of the technology. From Table 1, it would appear that adoption of hardware-based communication technologies, such as the VCR, TVRO, and the PC, is especially contingent upon certain demographic variables. The perceived relevance of such television attributes as picture sharpness and screen size for some prospective HDTV adopters contradicts the often-held view (e.g., Negroponte, 1995) that television characteristics and improvements are unimportant to the American public. Other things being equal (e.g., price), viewers prefer HDTV features to those of NTSC (Lupker et al., 1988). A recent HDTV-versus-NTSC comparative test, commissioned by Harris Corporation, further corroborates this assertion. Of the 104 respondents, 98% felt that digital HDTV was superior to traditional NTSC television; 96% stated that they liked the shape of the 16:9 receiver; and 97% reported that HDTV sound (5.1 channel system) was superior to NTSC sound (stereophony) (Harris Corporation, 1997). If indeed these HDTV attributes truly matter, U.S. broadcasters would be well inspired to transmit their programs in HDTV format, instead of delivering them in lower-resolution SDTV. This study also has practical implications for consumer electronics manufacturers. The good news is that a majority of respondents (58.3%) expressed an interest in HDTV and its features. On the other hand, only 15.5% of the sample reported a willingness to purchase an HDTV receiver at $3,000, an expected low-end figure for the first HDTV sets that will be introduced in the United States at the end of 1998. This percentage is similar to the one (14%) reported by Lupker et al. (1988) seven years earlier. Not surprisingly, and consistent with previous research (e.g., Dupagne & Agostino, 1991), an overwhelming majority (93.1%) of the respondents were either somewhat or very satisfied with their current television set. To overcome the price objection, which is likely to be acute in the initial diffusion of HDTV, consumer electronics marketers should adopt pull promotion strategies by stimulating interest and demand at the end-user level (instead of wholesalers and retailers), that is, targeting directly the consumer with advertising messages. Of particular importance, these campaigns should tout HDTV's relative advantages, such as picture sharpness and screen size. As discussed above, relative advantage is a key determinant of an innovation's rate of adoption (see Rogers, 1995). Finally, this research is not without weaknesses. The sample size is limited even for an exploratory study. It is also important to stress that the results derive from a single market, not from a national survey, although the sample composition was representative of the U.S. population at large in terms of age, gender, income, and ownership of home entertainment products. Furthermore, it may be argued that respondents' HDTV interest and purchase interest cannot be meaningfully measured without prior exposure to live demonstrations of HDTV pictures. A public demonstration would certainly have enhanced the relevance of consumer reactions. From this perspective, lack of context is another limitation of this study. On the other hand, unlike surveys or experiments presenting NTSC-HDTV side-by-side comparisons (e.g., Lupker et al., 1988; Neuman, 1988), this study has used a probabilistic procedure to select respondents, allowing greater external validity. Despite these limitations, the results of this research offers some preliminary diffusion-grounded insights into U.S. consumer awareness and interest in HDTV prior to its market introduction in the United States.
