The "Friday night death slot" or "Friday evening death slot" is a perceived graveyard slot in American television. It implies a television program in the United States scheduled on Friday evenings (typically, between 8:00 and 11:00 p.m. ET) is likely to be canceled. The term possibly began as a reflection of certain programs' dominance of Friday night in the 1980s and 1990s, which resulted in decreased ratings for those scheduled opposite their competitors.<ref name="voorhees">John Voorhees. "ABC reshuffles schedule for ratings but deals only two new shows," The Seattle Times, December 13, 1985, page C5: "Also being dropped is Our Family Honor, the ABC series that has had the distinction of being the lowest-rated Nielsen show almost every week since its debut.

The poor ratings in the time slot affected the show after it, Jerry Van Dyke's sitcom Accidental Family, leading to its failure after less than a season and angering Van Dyke, who was desperate for a hit and openly (but unsuccessfully) campaigned for NBC to give the show a better time slot. After Star Trek fans deluged NBC with a mail-in protest, producer Gene Roddenberry stated that he was promised the same 8:30–9:30 time slot for Season 3, but airing on Monday instead of Friday.
