After his first appearance on The Late Show with David Letterman in 1999, Gaffigan was tapped by the host to develop a sitcom called Welcome to New York in which he also co-starred alongside Christine Baranski. The show was cancelled after its first season despite receiving positive reviews. During the 2000/2001 television season, he was a cast member of The Ellen Show on CBS, Ellen DeGeneres's second sitcom.
