Crimetime Saturday

Crimetime Saturday is the official branding for a programming block that started in 2004–05 on the American CBS and Canadian CTV networks Saturday nights. However, the branding is only listed by CBS and industry sources as a placeholder for the time slot, and not as an official on-air branding for the night.
The first two hours feature reruns of CBS's crime drama procedural series, which over the years have included the four series of the "CSI" franchise, "Criminal Minds", "NCIS", "", "Cold Case", "Flashpoint" (before its move to Ion Television), "The Mentalist", "Blue Bloods" and "FBI", 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. Several times a year "48 Hours" will air two-hour specials or consecutive episodes.
Beginning in the 2011–2012 season, the block was reduced to two hours from three to make room for "Comedytime Saturday", a one-hour sitcom block, from 8 to 9 p.m. ET/PT. However, that hour was restored to "Crimetime" for the 2012–2013 season due to that block never being executed as planned and becoming a basic hour of repeat sitcoms. In a few cases, burned off shows such as "Made in Jersey" have aired in the first or both hours to minimize ratings damage, along with a new episode of "Vegas" in mid-April 2013 pushed up by a night due to CBS News coverage of the apprehension of the Boston Marathon bombing suspect.
The "Crimetime" block was re-reduced to two hours of Saturday night for the 2013–2014 season with the return of "Comedytime Saturday", but returned for the full three hours in the 2014–2015 season after a reduction of CBS's comedy schedule.
