Microsoft kicked of its week-long appeal of the European Commission\u2019s 2004 anti-trust ruling Monday with a searing attack on the competition regulator\u2019s arguments for ruling against the bundling of Media Player in Windows.The Commission argued in 2004 that by including its own music and video streaming software, branded Media Player, in its ubiquitous operating system, Microsoft would stifle competition in this important sector of the software market.Jean-Francois Bellis, from the Belgian law firm Van Bael & Bellis and Microsoft\u2019s lead lawyer on the bundling issue of the appeal, said that evidence from the market showed that the commission's reasoning was flawed."PC makers already put more than one player on their PCs," he said. RealPlayer from RealNetworks, which was one of the pioneers of streaming music and video content during the 1990s, "was widely distributed at the time of the commission's decision," he added.The vast majority of Web-site content providers design their music and video content to work using at least two media players, and 85% of end users used at least one non-Microsoft player, according to figures presented by Microsoft to the court.There was no evidence at the time of the ruling in 2004 of the market "tipping" in favor of Microsoft, according to Bellis. "The Commission decision must be rejected as it is disproved by events in the market," he said. "The absence of evidence of tipping is a striking repudiation of the Commission\u2019s theory."Since the 2004 ruling, Microsoft has launched XP edition N, as required by the European regulator. XP edition N has the media player stripped out but it sells at the same price as the normal version of Windows XP.To date, not one order for edition N has been placed by PC manufacturers, Bellis said, and only 1,787 have been ordered by computer stores across Europe in the nine months since it went on sale. This is equal to 0.005 percent of all XP sales in Europe during the same time period, he said.The court appeal is being heard by 13 judges of the court of first instance, Europe's second highest court, under the presidency of judge Bo Vesterdorf. The appeal will last all week and the final word of the court is expected between six months and a year from now.
