Will it play in Peoria?

Will it play in Peoria? is an American English figure of speech that is traditionally used to ask whether a given product, person, promotional theme, or event will appeal to mainstream audiences or across a broad range of demographic and psychographic groups in the United States.

The phrase is believed to have originated from the popularity of Peoria, Illinois as a stop on the vaudeville circuit, where acts would gauge new material by how well it was received by Peoria audiences, using Peoria as a test market.
