The Fresh Prince of Bel-Air is an American sitcom that originally aired on NBC from September 10, 1990, to May 20, 1996.
I did some research... [Willard Christopher Will Smith, Jr. (born September 25, *1968*)] was nearly bankrupt in *1990* when the NBC television network signed him to a contract and built a sitcom, The Fresh Prince of Bel-Air, around him. He was 21 or 22 years old, believe it or not. Source(s): Wikipedia.
