RealNetworks has maintained an edge over rival Microsoft in streaming-media technology, according to a Jupiter Media Metrix report. In November, about 28 percent of consumers who use computers in U.S. homes chose RealNetworks' RealPlayer to watch videos or listen to music online. That same month, 22 percent used Microsoft's Windows Media Player 6 or 7. Apple's QuickTime was used by 4 percent. The report, however, showed that consumers frequently switched media players, indicating a lack of brand loyalty.
