September 5, 1971. NBC tries something new: a rotating "wheel" of 90-minute crime stories. The original trio were all classics: Columbo, McCloud, and McMillan and Wife. Over the next five years the show changed days, lengths, spun off a clone, and added other series. Some highlights included, Quincy ME, Banacek, Lanigan's Rabbi, and Hec Ramsey.
