"Columbo" isn't the typical detective whodunit TV show. On most detective shows, viewers don't know who committed the crime until the detective pieces the clues together and figures it out. On this show, however, viewers see the crime unfold at the beginning of most episodes, including who the perpetrator is. The mystery and fun for viewers is trying to spot the clues that will lead Lt. Columbo (Peter Falk) to discover the culprit and watching the tricks he uses to get a confession. Episodes of "Columbo" were movie-length and ran sporadically on multiple networks during its run.
