People still watch Conan? I remember the big campaign when he moved to TBS after the Tonight Show debacle. I really thought he lost a lot of steam. My guess would've been either Letterman or Fallon.
I'm not sure of the numbers... But I thought the whole debacle only added to his steam... I was all over the news, therefore putting Conan's name out there to people who have only heard of Leno or Letterman
