The U.S. Department of Justice’s investigation of Apple’s alleged anti-competitive practices has grown to include video and other forms of multimedia, the New York Post is reporting. Citing multiple sources, the Post claims that the DoJ has queried several major media companies asking whether or not they feel Apple is in a position of undue influence over their products. A similar investigation focusing on Apple’s dominance in digital music was said to have commenced earlier this week. Whether or not this will eventually lead to a full-blown antitrust lawsuit being slapped against Apple is unclear, but it seems logical that if anyone is going want to do battle with Apple it’s the tough-talking Hollywood folk. As one of the Post’s insiders said, “you can’t dictate terms to the industry.” Trust us, we know.
