Using a 2004 cross-sectional database of digital cable systems in the U.S., we provide new evidence that the effects of vertical ownership ties between systems and programming suppliers persist in spite of extensive channel capacity expansion, as well as new competition from direct broadcast satellites. Focusing on four program network groups (basic outdoor entertainment, basic cartoon, basic movie, and premium movie), we generally find that integrated cable systems carry their affiliated networks more frequently and carry unaffiliated rival networks less frequently—a pattern identified by previous studies using data prior to DBS or the capacity expansion effects of digital cable. We also find that integrated systems that do carry rival networks often position them on digital tiers having more limited subscriber access, a pattern not investigated in previous studies.  相似文献

Based on the concept of experience economy, this study starts off by proposing that goods, services, and experiences are dimensions of experience-oriented service functions, illustrating an integrated approach which adopts the basic Kano model and customer satisfaction coefficients matrix to categorize and prioritize experience-oriented service functions. An empirical study was then conducted to explore customer need attributes for digital television (DTV) applications. As a result, 445 samples in Taiwan are collected and analyzed, showing different segments have different need attributes. In addition, a comparative analysis of experience-oriented customer needs for experienced and inexperienced users was applied in order to provide differentiated and continuous competitiveness during different stages of the product life cycle; then the result was used as a reference for future development of experience-oriented service functions.  相似文献

Broadband over cable television networks has become a growing force on the retail market in the EU. Thus, a debate has always been raised whether cable television networks should also be subject to open internet access obligations as PSTN and fibre. This article aims to share its view from a legal perspective. In order to do so, it conducts a survey of the current regulatory measures on broadband over cable television networks within the 27 EU Member States, and then carries out an in-depth legal analysis on Member States that attempted to regulate broadband over cable television networks. The conclusion is that broadband over cable television networks is currently deregulated, and will probably remain so in the future.  相似文献

以协同治理为理论基础,运用SFIC模型,从起始条件、催化领导、制度设计和协商过程4个方面研究发现,电视问政在主体参与动力、政府作用发挥、制度设计建构、持续常态发展方面存在不足。为回应以上问题,提出构建主体激励机制、政府促进机制、选题监督机制和长效持久机制的对策。  相似文献
