Sad but true. NBC's aim to rid youtube of anything related to their shows is seriously hurting them. Conan's ratings are going down and Fergusons going up, a lot of news sources attributing it to youtube. NBC and CBS's official youtube channels aside, NBC is constantly scouring and taking down any Conan videos people post, while CBS doesn't care that people post Ferguson clips. They made the obvious realization that fan posted videos generate more hype and viewers than tightly-controlled distribution. NBC are being waaay too corporate, especially on a video sharing website where EVERYONE sees through it.
In closing, rethink things NBC. Conan's segments are extremely entertaining and on youtube are GOLD with regards to viewership and web linkage. You taking down everything is killing your own ratings.
