For those of you out of the know, "jumping the shark" means that the program (or station in this case) has finally hit a point where it's suddenly on decline. It is usually tied in to a sitcom, a desparate plea for higher ratings (a wedding, a child is born, celebri) or a point of no return when a character is replaced. Of if Ted McGinley suddenly appears on your show. This was named after the episode of Happy Days when Fonzie jumped the shark.
