Jumping the shark is an idiom used to describe the moment of a misguided attempt at generating new publicity for something once, but no longer, widely popular; the attempt serves instead to highlight the irrelevance of what it intends to promote. This is especially applicable to television series or other entertainment outlets. The phrase derives from a 1977 episode of the sitcom Happy Days.
