Audio streaming service TuneIn relaunches its mobile app

What do you do to improve a service with over 50 million active users? Why, totally revamp it of course. It sounds crazy, but that’s exactly what TuneIn, an audio service that lets you listen to podcasts and radio stations from around the world, did. Before, TuneIn was more like a directory with a search engine. Now, it’s a full-blown audio network, which CEO John Donham says is the first of its kind.
