A broad settlement between digital media pioneer RealNetworks Inc. and its longtime foe Microsoft Corp. goes a lot further than simply ending the last major U.S. antitrust case against the tech heavyweight.

The settlement starts with a $460 million cash payment that settles all antitrust disputes worldwide that RealNetworks had against Microsoft. RealNetworks also gets $301 million in cash and services - including promotion on Microsoft Web sites and the software giant's instant-messaging service - that are designed to help its products reach a wider audience.

Seattle-based RealNetworks sued Microsoft in December 2003, accusing it of illegally forcing Windows users to accept Microsoft's digital media player. RealNetworks said its player suffered as a result.

RealNetworks also had participated in European Union and Korean antitrust complaints against Microsoft, but withdraws from those cases as part of the agreement.

Among other agreements, Microsoft's MSN online unit will feature RealNetworks' Rhapsody music subscription service on its MSN Music download site. It also will provide links in its MSN Search results that let people listen to songs through Rhapsody. RealNetworks also will take steps to support Microsoft's MSN Search, and the companies agreed to jointly promote use of Windows Media technologies with Rhapsody To Go, a music subscription services for portable devices. Microsoft also will offer digital games from Real through MSN Games and an upcoming version of its Xbox Live online game service.
