Broadcast weekdays on CBS Radio from 1943 to 1955, the series was adapted into The Edge of Night which ran on television for an additional 30 years. The 15-minute continuing series Perry Mason aired weekdays October 18, 1943 – December 30, 1955, on CBS Radio. Geared more towards action than courtroom drama, it mixed mystery and soap opera, with attorney Perry Mason sometimes even exchanging gunfire with criminals. Erle Stanley Gardner's literary success with the Perry Mason novels convinced Warner Bros. to try its hand, unsuccessfully, with some motion pictures. However, the Perry Mason radio show stayed on the air for 12 years. As The Edge of Night, it ran for another 30 years on television, but Gardner disliked the proposed daytime television version due to a lack of his own creative control. He ultimately withheld his endorsement of the daytime TV show, forcing the name change. (Source: Wikipedia)
