 Viacom cited internal e-mails sent among YouTube's founders discussing how to deal with clips uploaded to YouTube that were obviously the property of major media conglomerates.Google stated that Viacom itself had "hired no fewer than 18 different marketing agencies to upload its content to the site".Google argued that since Viacom and its lawyers were "unable to recognize that dozens of the clips alleged as infringements in this case were uploaded to YouTube with Viacom's express authorization, "it was unreasonable to expect Google's employees to know which videos were uploaded without permission."
