Launched in 2010, Rdio offers ad-free, subscription Internet radio for a wide range of mobile devices, streaming boxes and PCs. The service features sharing and social media integration, and songs can be cached for offline playback. Rdio does not release subscriber numbers.
The company charges a $10 monthly fee for its full service (half that for web-only), but in October Rdio announced a new streaming service that is free to users. Unlike competitors, the free version does not serve up ads, but it does restrict users from choosing songs.
Besides being forced to offer up a free service in October to meet competition (which reportedly tripled its total number of users), Rdio was in headlines this month with the news that it was laying off staff — between one-fifth and one-third of employees, according to TechCrunch.
