Usage Problem Usage Note: Debut is widely used as a verb, both intransitively (Her new series will debut next March on network television) and transitively (The network will debut her new series next March). These usages are well established in connection with entertainment and the performing arts but are not entirely acceptable when used of other sorts of introductions, as of products (The company will debut the new six-cylinder convertible next fall) or publications (The national edition of the newspaper debuted last summer), probably because of the association of the form with the language of show-business publicity.
