The "Friday night death slot" or "Friday evening death slot" is a perceived graveyard slot in American television. It implies that a television program in the United States scheduled on Friday evenings (typically, between 8:00 and 11:00 p.m. ET) is destined for cancellation.
The term possibly began as a reflection of certain shows' dominance of Friday night in the 1980s and 1990s, which condemned to death any television show scheduled opposite those programs. Today, it reflects the belief that young, single Americans rarely watch television on Friday or Saturday nights, thereby removing from the household the most lucrative demographic for advertisers.
TGIF was a successful block for ABC, which ran from 1989 to 2000 (although the network had been running a sitcom block on Fridays beginning in 1987); it focused primarily on family-friendly sitcoms. The network had also had success with a block featuring The Partridge Family and The Brady Bunch in the same time slots during the early 1970s. Following the slow collapse of TGIF in the late 1990s, Friday night has fallen into a lower priority for the network. The following are examples of ABC network shows that started on Friday nights and lasted a few episodes, or were moved to Friday nights, lost the battle for television ratings, and were eventually canceled:
Perhaps the network which has received the most attention and has become the most well known for the "Friday Night Death Slot" has been Fox.
