传播学视野下的影视植入广告

在影视作品中植入广告的营销方式并不新鲜,当前的问题是很多广告的植入严重存在着盲目性。在传播学视野下,成功的广告植入必须保证编码的有效性,即针对特定的受众、特定的情节,特定的时机选择匹配的产品;注重产品品牌的符号信息与影视作品内容的相互构建,从中充分发挥符号互动的张力,使其影响的范围更广、时效性更长,从而达到潜移默化的宣传效果,实现最佳的营销目的。     

Television Advertising Avoidance: Advancing Research Methodology

New technologies have led to increased television advertising avoidance. In particular, mechanical avoidance in the form of zipping and zapping has gained momentum in recent years. Channel switching or “commercial zapping” studies employ diverse methodologies, including self reports, electronic monitoring, laboratory, and in-home observation which has led to a diversity of reported results. This article proposes advancing and standardizing the methodology to comprise a two-phase hidden observation and survey method. A number of research phases have led to the development of this method to collect both mechanical and behavioral avoidance data. The study includes a detailed outline of the hidden observation approach. The survey phase opens up the potential for the collection of viewer data that may further illuminate television advertising avoidance behavior.

Cable Television Rate Deregulation

In the 1984 Cable Communications Policy Act, cable television operators were effectively freed from rate regulation, and subsequently enjoyed monopoly franchise protection with free market pricing. In 1992, however, reregulation of basic cable service rates was established in the Cable Consumer Protection and Competition Act. The argument for reimposing regulation was that a substantial increase in basic cable rates had occurred post–deregulation. Yet the efficacy of rate controls upon an industry which has substantial freedom to adjust product quality is theoretically ambiguous. This study examines simple price, quality, and output evidence to determine how rate deregulation impacted consumers. It finds support for the view that rate controls did not lower quality–adjusted prices and are best explained as tools for influencing rent distribution across interest groups

The discriminatory incentives to bundle in the cable television industry

An influential theoretical literature supports a discriminatory explanation for product bundling: it reduces consumer heterogeneity, extracting surplus in a manner similar to second-degree price discrimination. This paper tests this theory and quantifies its importance in the cable television industry. The results provide qualified support for the theory. While bundling of general-interest cable networks is estimated to have no discriminatory effect, bundling an average top-15 special-interest cable network significantly increases the estimated elasticity of cable demand. Calibrating these results to a simple model of bundle demand with normally distributed tastes suggests that such bundling yields a heterogeneity reduction equal to a 4.7% increase in firm profits (and 4.0% reduction in consumers surplus). The results are robust to alternative explanations for bundling.

On the Ethics of Product Placement in Media Entertainment

Abstract

This study examines the ethical propriety of current trends in product placement in television and film entertainment. Historical background for the product placement concept and practice is provided. Changes in the marketing climate that have provided a push for product placement are outlined. A characterization of the product placement industry as it stands today, and the ethical issues raised by the practice frame the analysis. Three distinct “genres” of contemporary product placement are analyzed: (1) Product Placement, (2) Product Integration, and (3) Video Insertion. First, the rise of Product Placement, strategic changes in use, and increased dependence on revenues in production will be discussed. The second section examines a newly mounted form of Product Integration, whereby product placement plays a key role in content development and support of production in television and film. Third, the origins of Video Insertion will be traced to the Princeton Video Image invention of its proprietary L-VIS product. The ethical efficacy ofplacing “virtual advertisements” in space and times that do not naturally exist will be examined. The article closes with summary assessments and consideration of recommendations for action. Ethical issues focused on in the assessment include deception, artists' rights, and excess commercialism. Recommendations consider the climate for full and advance disclosure of product placements in media entertainment, the prospects for a voluntary rating system, and the threat of reclassifying product placement infused media entertainment as commercial speech.     

Understanding Physical Inactivity: Prediction of Four Sedentary Leisure Behaviors

An understanding of the motives underlying sedentary leisure behavior may guide interventions to decrease these behaviors. The purpose of this study was to apply the theory of planned behavior (TPB) to understand the motives underlying four common sedentary leisure activities: television viewing, computer use, reading/music, and socializing. A cross-sectional community sample of 206 adults and 174 undergraduate students completed measures of the TPB of these four leisure behaviors and self-reported behavior. Results using ordinary least squares regression provided evidence that sedentary behaviors may be intentional and planned with a primary attitude base but not related to perceived behavioral control. The findings provide information about sedentary behavior motivation and support the validity of the TPB for the prediction of these behaviors.
