The Jim Henson Hour is a short-lived television series that aired on NBC in 1989. It was developed as a showcase for The Jim Henson Company's various puppet creations, including the popular Muppet characters. Only nine of the twelve episodes produced managed to air on NBC before the low-rated program was cancelled. Two later aired on Nickelodeon in 1992 and 1993, and the final episode never aired in the US, but it did air in the UK in 1990..
