In other news, four of the largest media corporations here in this country have asked the Supreme Court to review a lower court ruling that has blocked the companies from greatly expanding. The media companies filed the appeal on Friday, a day after the Bush administration announced it would not appeal the court ruling. Viacom (which owns CBS), General Electric (which owns NBC), News Corp. (which owns Fox) and the Tribune Company filed a joint petition with the Supreme Court with hopes that the high court would rule the Federal Communications Commission can go ahead and implement a series of sweeping media ownership rule changes that would lead to dramatic consolidation of the country’s media outlets. If the Supreme Court backs the media companies, a single company would soon be allowed to own as many as three television stations, eight radio stations, a cable operator, and a newspaper in a single city.
