In 2007, media giant Viacom sued YouTube for $1 billion, alleging that the website had committed massive copyright infringement by posting thousands of Viacom-produced videos without permission. Over the next seven years, the two companies battled it out in the U.S. District Court for the Southern District of New York. In 2010, YouTube accused Viacom of hiring no fewer than 18 marketing agencies to “continuously and secretly” upload Viacom videos to YouTube. In 2013, Viacom submitted internal YouTube e-mails indicating that the YouTube staff knew that the site was “out of control with copyrighted material,” but that they decided to ignore it. And in April of last year, District Court judge Louis Stanton ruled in favor of YouTube. The parties settled the matter out of court last week, less than a week before oral arguments were scheduled to proceed in Viacom’s appeal.
