Free online radio removed from MSN 

June 19, 2008 -- As quietly as it launched on Microsoft's site two years ago, internet radio service Pandora was discontinued from MSN around midnight Wednesday. Pandora remains on its own web site, and user settings are unaffected.

Pandora, which was the home page for, was replaced by a message reading: "MSN Music has discontinued its radio service. Search for radio stations and related services."

Speculation on the decision ranges from a lack of Pandora revenue relative to RIAA royalties, to personal bias among Microsoft management. It is not believed to be Pandora's decision, however the online radio provider may have been too cautious about monetizing the audience with advertising.

Recently, more sites have been using interstitials, or rich media such as ZeroKlix.

Pandora's service is considered legendary by some. A Seattle DJ and Pandora fan Aaron Walters said, "I don't know what it means for Pandora to lose Microsoft, but I guess I'll just change my bookmark."

In 2006, the Wall Street Journal reported, "Pandora's team of music analysts take songs apart, assigning values to as many as 400 musical nuances per song; the service then uses that information to compare songs and make recommendations."

Users can create multiple channels, skip songs, and vote them up or down. Royalties for allowing users to select exactly what songs to listen to would be cost prohibitive. For most broadcasters, bandwidth and royalty costs are already too high for profitability. But when one service turns off, another is likely to take its place.

In Spring 2008, it was reported Pandora had more than eight million registered listeners with 2.75 million unique visitors monthly and a database of over 400,000 songs.
