Using TV Daypart ‘Double Jeopardy Effects’ to Boost Advertising Efficiency
研究通过分析电视时段内的观众留存率，发现高收视节目不仅观众更多，忠诚度也更高，并据此提出新的媒体购买策略，在不牺牲覆盖面的前提下提升广告曝光频率。
Several TV audience studies have revealed a ‘Double Jeopardy effect’ whereby highly rated programs generate not only more viewers but also disproportionately more loyal viewers than lower-rated programs. In these cases, loyalty was measured as weekly or daily repeat viewing of an individual program. This study expands on prior work by introducing a different operationalization of audience loyalty, namely audience turnover revealed within multi-hour dayparts. By concentrating on continuous audience retention, the researchers demonstrate how this approach could yield new media-buying strategies in terms of boosting frequency of exposure without sacrificing reach. Over 100 Nielsen diary-based sweep markets were analyzed to confirm that a double-jeopardy effect does in fact exist using this different methodology.
