Let's face it, videos of Jon Stewart and Stephen Colbert comprise a significant share of what is actually funny on YouTube. Viacom apparently wants others to provide the humor, as Reuters reports the company has demanded YouTube take down every Viacom video, estimated at around 100,000. One buzz at CES last month was the fact that YouTube had promised to implement technology that could filter content from studios by year-end but had failed to do so. This report seems to indicate that Viacom isn't willing to wait any longer.

UPDATE: Kudos to YouTube, which quickly said they would act on Viacom's request.
