Google ended its three-year affair with trying to break into radio Thursday, with the company saying it is selling its Radio Automation business. Google in 2006, launched Google Audio Ads and Google Radio Automation after buying dMarc Broadcasting, Inc for $102.0 million. Google made the move in the hope of transforming how radio ads are bought, aiming to streamline the entire process. The company said these plans, however, “haven’t had the impact we hoped for.”

Google said it will turn its focus from radio to online streaming audio. It will phase out the existing Google Audio Ads and AdSense for Audio products and plans to sell Google Radio Automation – the software that automates broadcast radio programming. [Forbes.com]

Hmm. A couple of ways to interpret this.
