The profile of African-Caribbean actors on television, such as Lennie James, Judith Jacob and Diane Parish, has widened substantially since 1970s programmes such as: "Love Thy Neighbour" (Rudolph Walker) and "Rising Damp" (Don Warrington) when their role was often to act simply as either the butt of, or foil to, racist jokes made by White characters. The most influential programme in moving away from this formula was the 1989–94 Channel Four barbershop sitcom "Desmond's", starring Norman Beaton and Carmen Munroe. In 1982, at the time, the youngest ever actor to play Doctor Who, Peter Davison is of Afro-Guyanese and English descent.
