America's Most Wanted is an American television program whose first run was produced by 20th Television, and second run is under the Fox Alternative Entertainment division of Fox Corporation. At the time of its cancellation by the Fox television network in June 2011, it was the longest-running program in the network's history, a mark since surpassed by The Simpsons, although the program was revived ten years later. The show started off as a half-hour program on February 7, 1988. In 1990, the show's format was changed from 30 minutes to 60 minutes. The show's format was reverted to 30 minutes in 1995, and then back to 60 minutes in 1996. A short-lived syndicated spinoff titled America's Most Wanted: Final Justice aired during the 1995–96 season.
