21 Jump Street

21 Jump Street is an American police procedural drama television series created by Patrick Hasburgh and Stephen J. Cannell for the Fox Broadcasting Company. It aired from April 12, 1987, to April 27, 1991, spanning 103 episodes over five seasons; the final season aired in first-run syndication. The series focuses on a squad of youthful-looking undercover police officers investigating crimes in schools, gangs, and other teenage venues. It was originally going to be titled Jump Street Chapel, after the deconsecrated church building in which the unit is headquartered, but was changed at Fox's request so as not to mislead viewers into thinking it was a religious program.
