TargetSpot added partnerships with broadcasters Beasley Broadcast Group, Rubber City Radio Group and Haystack Media.
The company is an in-stream advertising service; it went live this month and says it will soon be available on 400 stations. Previous deals were reached with CBS Radio, Entercom Communications and WarpRadio.
The technology allows businesses to create, buy and place their own advertising messages within streaming media.
Advertisers can create customized audio, video, banner and text ads including jingles, sound effects and visuals. Clients can also upload creative into their TargetSpot account. Ads are targeted to a specific demographic, location and/or station.
Costs vary with ad revenue being shared among TargetSpot and the broadcaster.
