Promoting prime‐time programs in megasporting events

Analysis of 677 promos for prime‐time series carried within 1993 and 1994 sporting events on the major broadcast networks showed that most on‐air promotion had a modest impact on program shares and ratings: about one‐third of shares went up, over one‐half stayed flat, and less than 10% went down. A six‐part model incorporating lead‐in shares/rating, three structural factors, and two presentational factors collectively accounted for about one‐third of the variance in promoted prime‐time series’ shares and ratings.
