RealPlayer was a dominant player in the streaming video business and had created a two sided market out of which the consumers were the subsidized side.

The content providers saw no point in continuing using Real and moved to windows platform threatening the existence of Real. Windows could afford to do so since the provision of such a service boosted their sales of the OS and the mass adoption of the Windows Media Player on the consumer side which was the only compatible player with the windows streaming platform."@en . . . . . . . . . .
