The two had a natural chemistry, in which Carolla's jocular tone emphasized Pinsky's reasoned expertise. Together, they refined the format of the show, and capitalized on their growing popularity with speaking tours, a television show on MTV (also titled Loveline), a book, and cameo appearances on television series and movies. In November 2005, Carolla left Loveline to prepare for a new morning radio show, The Adam Carolla Show, which began airing in January 2006.
