Crimetime Saturday is the official branding for a programming block that started in 2004–05 on the American CBS and Canadian CTV networks between 9 and 11 p.m. ET/PT on Saturday nights. However, the branding is only listed by industry sources as a placeholder for the time slot, and not as an official on-air branding for night.
The first hour features reruns of CBS's crime drama procedural series, which include the three series of the CSI franchise, Criminal Minds, NCIS, NCIS: Los Angeles, Cold Case (prior to its cancellation) and The Mentalist, with the final hour featuring a new or encore edition of the CBS News newsmagazine program 48 Hours Mystery, which focuses on true crime stories.
Beginning in the 2011 season, the block was reduced to two hours from three to make room for Comedytime Saturday, a one-hour sitcom block, from 8–9 p.m. ET/PT.
