Real Networks Inc has unveiled a Radio Toolkit, Rolling Stone Radio and the beta of a pay-per-listen jukebox in a raft of announcements timed to coincide with the WebNoize conference in Los Angeles this week. The company says that its radio toolkit will give broadcasters and music programmers the integration, caching, e-commerce linking and other features they need to create new radio businesses on the internet. JAMTV/Rolling Stone Network is the first to fall for the pitch, but others, including ABC Radio Stations and Spinner.com, have pledged their support. Meanwhile, Sony Music Online is hosting the beta of a pay-per-listen jukebox based on RealNetworks’ RealPlayer web client.
