MasterChef is a BBC television cookery game show. It ran initially from 1990 to 2001, and was revived in a different format as MasterChef Goes Large from 2005 onwards. The "Goes Large" part of the name was dropped in 2008 but the format remains identical. The revamped format was devised by Karen Ross and John Silver, who updated the original Franc Roddam format. The series now appears in three versions: the main MasterChef series, MasterChef: The Professionals for working chefs, and Celebrity MasterChef. All three versions have been commissioned up to and including 2011. A further version, Junior Masterchef, for 10-to-12-year-olds, was also broadcast in 2010.
