More Ads, More Viewers? Analyzing Behavioral Shifts from Advertising Permissions to Live Streaming Consumption
研究直播平台允许主播插入中插广告对观众消费的影响，发现广告许可反而增加了观看时长和观众数量，原因在于主播增加了播出时间和质量。
There has been little exploration of how audience content consumption may change in response to advertising permissions on live streaming platforms. Brands use ads to generate revenue through ad exposure, but is this benefit thwarted by the reduction of audience consumption of content? Using a dataset containing over 12 million observations in the live streaming space and a difference-in-differences estimation approach, the authors study the effects of a policy intervention by a live streaming platform that provided (some) streamers the ability to display midroll advertisements. Although the ad avoidance literature infers that audiences view ad-supported content unfavorably, the results of this study indicate that providing the mere ability to introduce midroll advertisements has a notable positive effect on live streaming content consumption (average viewership and total hours watched). The authors discover that a viable explanation for this response is through increases in broadcasting airtime, stream frequency (somewhat), and quality by streamers after the intervention, as these adjustments are drastically easier to implement in a live streaming setting than in more traditional forms of media. The authors further explore heterogeneity in these effects in relation to initial streamer success, streaming tenure, content activity, culture (of the streamer and audience), and impact across time.
