Introduction According to Internet World Stats,the totalnumber of internet users in the world in 2014 exceeded 3 billion (internetworldstats.com, 2014). Moreover, the growth rate this represents in terms of the number of internet users is about 741 per cent compared year-on-year with the number of users in 2000 (internetworldstats.com,2014).An investigation carried out by the Institute for Information Industry (III) in Taiwan revealed that as of June 2013, the total number of households connected to a wired broadband network had reached 5.38 million, the number of internet users could exceed 11 million and the penetration rate of internet usage had reached 48 per cent in Taiwan (Find.com,2014b).Another investigation by the III indicated that the number of 3G/4G mobile online users has reached 10.5 million, with more than 50 per cent of the users watching TV programs on video websites, such as YouTube (Find.com, 2014a). Online video advertisement exerts a wide-ranging influence on the internet, and provides huge opportunities for business enterprises. The revenues of website service providers come mostly from advertisement.This study specifically focuses on YouTube,one of the most well-known online video sites, and aims to address the following research questions: RQ1.What are the Web advertising variables that affect customers’ attitudes? RQ2.Does flow influence the purchase intention and shopping behavior after watching the online video advertising? RQ3.Do video consumers’ attitudes influence the shopping intention after watching the online video advertisement? This research establishes an online video advertisement attitude model integrating the Web advertising attitude model developed by Brackett and Carr (2001)modelas the basis for extending their study. Our model also incorporates the theory of reasoned action (TRA) and flow theory.Ducoffe(1996)indicated thatonlineadvertising valueisa measureof advertising effectiveness. His researchfindings showed the role of advertising value in Web advertising context and examined the determinants of advertising value.In other words, when consumers watch online advertising, they may need to know the product information (informativeness), plus some enjoyment or emotional release (entertainment) and trust of the product or brand (credibility).In contrast,consumers may not be disturbed by advertising when they navigate the webpage (irritation).Hsu and Lu (2004) indicated that flow is an criticalpredictor of purchase intention in the advertising research model.Flow is a fully immersed state that people undergo when they act with the environment (Csikszentmihalyi, 1997).Flow is a kind of mental concentration in Web browsing or navigation (Erkan and Evans,2016).Hence,flow is an important factor for customers to increase the purchase intention in e-commerce (Gao and Koufaris, 2006; Yan et al., 2016). It is crucial to identify the antecedents of advertising attitudes and flow experience more carefully,and to integrate these variables into a comprehensive model that can provide a clear understanding of how these factors influence shopping intention and purchase behavior. Thisresearch providesatheoreticalunderstanding and extension oftheonline advertising model. Ourfindings show that the model identifies the crucial factors in terms of attitudes toward advertisement in online video services, such as YouTube. Thefindings can provide for academic and practitioner reference. Literature review and hypothesis development Flow Csikszentmihalyi (1975) defined flow as the holistic sensation that people feel when they act with totalinvolvement.When people are in flow,they shiftinto a common mode of Online video advertisement 841 Downloaded by ECU Libraries At 19:02 14 January 2018 (PT)
experience when they become absorbed in their activity.This mode is characterized by a narrowing of the focus of awareness so that irrelevant perceptions and thoughts arefiltered out,by loss of self-consciousness,by a responsiveness to clear goals and unambiguous feedback and by a sense of control over the environment.Furthermore,Csikszentmihalyi (1997) characterizes online flow as involving machine interactivity,enjoyment and loss of self-consciousness,and as being self-reinforcing.Hoffman and Novak (1996) proposed that online flow is a cognitive state experienced during navigation. This cognitive state has been characterized as an optimal experience that is intrinsically enjoyable.Moreover,Hausman and Siekpe (2009)pointed outthatsome researchers view flow as centralto human– computer interactions and have empirically assessed the capacity of flow to explain the use of computer systems. Some studies demonstrate that flow is a critical predictor of purchase intention in the advertising research model (Kim and Han,2014).Flow is a kind of mental status that people concentrate in online surfing or navigation (Erkan and Evans,2016). Hence,flow plays a crucialfactor for customers to increase the purchase intention in e- commerce (Gao and Koufaris, 2006; Yan et al., 2016). Attitudes toward internet advertising Ducoffe (1996) demonstrated that entertainment,informativeness and irritation influenced attitudestowardWebadvertisements.Thecontent(informativeness)andform (entertainment)ofads are importantpredictors oftheirvalue and are crucialto the effectiveness of Web advertising, while irritation has negative impacts on viewer attitudes. Although some researchers have assumed that attitudes is an important construct of internet advertising (Ducoffe, 1996), Schlosser et al. (1999) thought it also plausible that the unique characteristics of the internet,when used primarily as an information-providing medium,might cause the underlying structure of attitudes toward internet advertising to differ.Their study viewed internet advertisements as more informative and trustworthy. They found notonly thatthe traditionalassessments ofadvertising effectiveness (i.e. considering the information and entertainment value)would apply to advertising on the Web, but also that the advertisement’s utility for making behavioral (purchasing) decisions would influence viewer attitudes toward internet advertising. Brackettand Carr (2001)thought thatattitudes toward online advertisements is the aggregation of weighted evaluations of perceived attributes and consequences of products, and they developed an integrated Web advertising attitude modelmodified from several earlier studies. The present research also uses this model as a basis to establish a new model of attitudes toward online video advertisements. Informativeness. Informativeness means that “consensus exists with regard to the ability of advertising to inform consumers of product alternatives”, and accordingly, the satisfying decision of purchasing can be made (Schlosser et al., 1999). The concept is extended from the users and gratifications theory (UGT).The UGT is an approach to realizing why and how people actively seek out specific media to satisfy specific needs.The UGT is an audience- centered approach to understanding mass communication.It assumes that video viewers are not passive consumers of media.Rather,these viewers have power over their media consumption and assume an active role in interpreting and integrating media into their own lives (Luo, 2002). Unlike other theoretical perspectives, the UGT assumes that audiences are responsible for choosing media to meettheir desires and needs to achieve gratification (Ruggiero, 2000).Many studies have shown the importance of informativeness to attitudes toward online advertisements (Andrews, 1989). Irritation.Irritation has the potentialto divertattention from worthy socialgoals (Galbraith and Crook,1958),dilutes human experiences (Boorstin et al.,1974) and exploits K 46,5 842 Downloaded by ECU Libraries At 19:02 14 January 2018 (PT)
