TGIF is the name of an American prime time television programming block that has aired on ABC at various points since the late 1980s. The name comes from the initials of the popular phrase ""; however, the stars of the lineup touted the initialism meaning "Thank Goodness It's Funny." In its various incarnations, the block mainly featured situation comedies aimed at a family audience, and served as a lead-in to the long-running newsmagazine "20/20" (which has been part of ABC's Friday night schedule since September 1987, two years prior to the original launch of "TGIF").
