Microsoft and RealNetworks have settled their long-running $750 million lawsuit.

A press conference featuring both Bill Gates and Real CEO Rob Glaser has been set for later today and, according to The Wall Street Journal, a deal has been reached where Microsoft will provide a combination of cash and promotions for RealNetworks' music and game services through Microsoft's online services and software, and the two companies would collaborate on technology initiatives in he future.

RealNetworks filed its anti-trust lawsuit against Microsoft in December 2003, alleging that Microsoft had used its Windows dominance to restrict RealNetworks' position in the market for media software on the PC.

The lawsuit claimed Microsoft forced PC manufacturers to include its Windows Media Player while at the same time placing restrictions on how competing players may be installed. RealNetworks initially claimed damages in excess of $1 billion.

Microsoft has already settled or resolved many of the big antitrust suits filed against it. Last April, it paid Sun $1.6 billion to settle charges against it. Before that, it paid the former AOL $750 million to settle a complaint from its Netscape division.

Microsoft is currently appealing a separate anti-trust ruling against it by the European Commission.
