Tradio (original) (raw)

Tradio is a type of talk radio show format, though now considered archaic, where listeners call in to buy or sell items. The concept is analogous to classified ads in local newspapers and most prevalent in the south and midwest. "Tradio" is a portmanteau of "trade" and "radio". The format is also often called Swap Shop; Buy, Sell, or Trade; Biz Baz; or Trading Post.
