Late night television is one of the dayparts in television broadcast programming. It follows prime time and precedes the overnight television show graveyard slot. The slot generally runs from about 11:00 p.m. to 2:00 a.m. ET, with variations according to the time zone and broadcaster. In the United States and Canada, the term is synonymous with the late-night talk show, a type of television comedy talk show and variety show. Thus, the late night programming block is considered more important in North America. On most major-network stations, a late-night news airs at the beginning of the block.
