Freemium continues to be a popular weapon in the music streaming wars, and today Rdio launched free streams for 6 months in 15 of the 17 countries in which it's available. The markets include the United States (where it's been free since Oct 2011), United Kingdom, Australia, Belgium, Canada, Denmark, Estonia, Finland, France, Netherlands, New Zealand, Norway, Portugal, Spain, and Sweden.
Rdio is not offering the 6 month free in Germany or Brazil. In the other markets new listeners can sign up and activate free streaming with no credit card required. The free offering does not include mobile apps.
Launched in August 2010, Rdio is headquartered in San Francisco and was founded by Janus Friis, the co-creator of Skype. Rdio is funded by Janus Friis through his investment entities, Atomico, and Skype.
