The latest research from Mark Kassof & Co. looks at P1 radio listeners and their station preferences. Christian format P1 have the highest level of preference for the station they listen to most, while CHR listeners have the lowest level.

Overall, 50 percent of listeners think their P1 station is "a lot better" than other stations they listen to. But of those who name a Christian station, that number is 73 percent. Other formats with above average station preference are Public Radio (64 percent), News/Talk (61 percent) and Country (56 percent).

CHR stations have the lowest preference among their P1 listeners: 39 percent think their station is a lot better (while 55 percent find it only "slightly better"). Other formats with "a lot better" scores below average are Oldies/Classic Hits (42 percent), Adult Contemporary (43 percent) and Sports (44 percent).

Kassof's research is based on 732 online surveys of 18-64 year olds in the U.S. who could name a station they "spend the most time listening to." Stations' formats were categorized based on their ID and market. The survey was conducted October 1-4, 2012. More details can be found at kassof.com.
