A tie-in work is a work of fiction or other product based on a media property such as a film, video game, television series, board game, website, role-playing game or literary property. Tie-ins are authorized by the owners of the original property, and are a form of cross-promotion used primarily to generate additional income from that property and to promote its visibility.

Tradio is a type of phone-in radio program formatted to provide a venue for listeners to freely advertise items they have to sell or trade.

The format is also often called Swap Shop; Buy, Sell, or Trade; Biz Baz; or Trading Post.
