Google's abortive love affair with radio is over. Thank goodness. I would argue that by getting in to the business of selling radio ads, Google was never really into the content side of radio. It was trying to do Adsense on commercial radio stations, becoming a threat to the radio sales dept of the radio station. It had no clue in this side of the business. Sounds like e-Bay and skype.
Radio urgently needs a Google-like service, being able to find interesting audio in an i-Player like environment. Radio is still struggling with the point and dial interface. Most radio station websites are a joke - a schedule and a button to listen live. Millions are being spent on radio programmes which are only available when on the air and difficult if not impossible to find later. Far from being a cheap medium, in developed countries its becoming a very expensive way to share an idea.
Google's radio automation software business has been sold to the US company called WideOrbit. They are now owners of the Maestro and SS32 automation products. But this is a very crowded market in an industry that has very little money at all at the moment. Don't they get problems with people giving their products a wide orbit?
