Similarly, antitrust lobbying is part of a broader “platform war” for IBM, which hopes thereby to keep Microsoft at bay. Among other things, IBM is a sponsor of the European Committee for Interoperable Systems (ECIS), which has many of Microsoft’s other competitors as its members and is one of the prime movers behind the new browser case. It started in late 2007 with a complaint by Opera, a Norwegian browser-maker and ECIS member.
Not to be outdone, Microsoft has entered the antitrust game, too. It recently made an investment in T3, a small vendor of mainframe-like computers, which in January lodged a complaint with the European Commission, alleging that IBM kept it from competing by refusing to license mainframe software to T3’s customers. Microsoft has also lobbied American antitrust regulators to tackle Google, encouraging them to look into an online-advertising deal between the search giant and its rival, Yahoo!, which was eventually abandoned.
