Zap2It: November 10, 2007 The following are all examples of CBS shows that either started on Friday nights and lasted a few episodes, or moved to Friday nights, lost the battle for television ratings, and were eventually cancelled: CBS has aired MacGyver, Hawaii Five-0 and Blue Bloods in that order on Friday night between 2016 and 2020. ABC 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.

According to Fox Entertainment President Kevin Reilly, nearly half of Fringes viewership time shifts the show to watch at their convenience, and that "if it does anywhere near what it did on Thursdays, we can glue that show to the schedule because it can be a big win for us". The Fox network created a promotional advertisement for Fringe that lampooned its reputation of the Friday night death slot prior to Fringes move. Despite encountering lower ratings after its move, Fringe was renewed for a fourth season, and later for a shortened final fifth
