Sports radio (or sports talk radio) is a radio format devoted entirely to discussion and broadcasting of sporting events. A widespread programming genre that has a narrow audience appeal, sports radio is characterized by an often-boisterous on-air style and extensive debate and analysis by both s and callers. Many sports talk stations also carry play-by-play of local sports teams as part of their regular programming. Hosted by Bill Mazer, the first sports talk radio show in history launched in March 1964 on New York's WNBC (AM).
