If you love an old-fashioned courtroom battle with a new media twist, the Google vs. Viacom copyright-infringement case makes for great entertainment. This lengthy (and particularly pissy) quarrel, which dates back to 2007, centers on Viacom's claim that Google's YouTube video-sharing site allowed users to upload more than 100,000 video clips from Viacom-owned networks and movie studios, including BET, Comedy Central, MTV, Nickelodeon, and Paramount Pictures. Viacom's lawsuit, filed in U.S. District Court for the Southern District of New York, seeks $1 billion in damages.
