Crimetime After Primetime

Crimetime After Primetime is the umbrella title for a group of late-night crime-investigation shows that debuted at various times on CBS during 1991 and 1992, running through late summer of 1993. 
History.
Prior to 1989, CBS aired the similarly formatted "CBS Late Night". The block was canceled to make way for "The Pat Sajak Show", a conventional late-night talk show. After the shortening, and eventual failure, of "The Pat Sajak Show", a revamped "CBS Late Night" block debuted, airing a variety of news, talk shows, reruns, and adult game shows.
In March 1991, after a two-month hiatus due to Gulf War coverage, CBS retooled the block by airing original series under the new umbrella title of "Crimetime After Primetime".
Much like "CBS Late Night" did in the late 1980s, "Crimetime After Primetime" relied heavily on dramas that were imported from Canada, giving the programs (most of which were produced to meet Canadian content quotas) an additional revenue stream. CBS also invested in producing some original series for the block.
The block was dropped when CBS began broadcasting the "Late Show with David Letterman" in August 1993.
