AdWhoIs.com maintains a database of actors and actresses by commercial, commercials by actor, and a user forum, "Who's In That Commercial?" Tumblr.com's "Who Is That Hot Ad Girl?," last updated in May 2015, identifies actresses in new and current commercials and has archives of entries for older commercials.
"Who Is That Hot Ad Girl?" accepts user submissions of commercials not listed in its database. WITHAG also hosts a community forum and a question-and-answer page.
The Internet Movie Database has user-generated lists of TV commercial actresses; the lists feature names of actresses in current commercials as well as from vintage ads.
