Scarborough Sports Marketing surveys respondents about their viewing/listening habits of different sports leagues over the previous 12 months. The following breaks down the demos for respondents who have watched MLB on TV or listened to MLB on radio within the past 12 months. For example, 61.7% of the respondents who watched MLB on TV within the past 12 months were men. The index compares each demographic category with somewhat/very avid MLB fans (i.e., men are 3% more likely to watch MLB on TV than somewhat/very avid MLB fans). The data was collected among 200,000 respondents from February '00 to March '01 (Scarborough).
