SAN FRANCISCO -- This afternoon RealNetworks (RNWK) - Get Report is the rare Internet stock that's up.

The gain in RealNetworks came despite news that

Microsoft

(MSFT) - Get Report

had formed a division focusing on streaming media, a development that could affect RealNetworks' business.

Microsoft said its new division will focus on technology for applications ranging from music, radio, news and events to online training and corporate communications. Microsoft already competes with RealNetworks with its Windows Media Player.

RealNetworks was up 9 3/8, or 5%, at 190 1/2. Microsoft was down 3/4, or 1%, at 83 1/4.

RealNetworks is expected to announce the launch of its new RealPlayer next week, which could be providing some strength, said Dan King, analyst with

LaSalle Street Securities
