"The phrase specifically arises from a scene in the hit TV comedy series Happy Days in which one of the central characters, Arthur "The Fonz" Fonzarelli, on water skis, literally jumps over a shark. The scene was written into the show at a point when the viewing ratings were beginning to drop, and it is generally regarded as the creative low-point at which the show finally lost all credibility. A show may continue well after the point when fans feel it has "jumped the shark" but will likely decline in popularity."
Wikipedia has jumped the shark.
