Umm, Pretty sure NBC refused to release Jay from his contract and wanted to move him to Primetime because they thought he would go somewhere else for a while.
Again NBC's decision because they wouldn't let Leno out of his contract and if Leno just left that meant he would be sued by NBC.
Okay so NBC coming to Leno and stating they wanted to take the Jay Leno show down to half an hour, move it to 11:35 and push Conan and the Tonight Show back One half hour is such a big deal.
I don't know how much successful people you have ever really been around but to be honest, I have a lot of them around me and I've always been the nice courteous guy that doesn't want to make people mad, but the successful ones are asses, they are tough and do what it takes to succeed and not just be a doormat. There is an unwritten rule in life that you should go by and that is looking out for number 1(yourself, your family, all things immediately revolving around you). You have to do it or you will be ran over.
The guy may have done some "douchebag" things but you cannot blame him for something that wouldn't even be happening in the first place had the focal point of your argument (Conan being the best late night show host on tv) been true and people tuned in.
You are trying to pin all of these excuses on Jay Leno but there are reasons behind things. If Leno was so bad, why'd he get the ratings. Its completely logical to move Leno back to 11:35 where he has captured more viewers than Letterman for many years for just 30 minutes and then lead in with that large audience to Conan with the majority viewers to beat out Letterman for the second half of Letterman's show.
Its almost like hearing an argument that if the Lions drafted better they'd be in a better position now. They had their shot and missed it. Conan got a shot, then was told he was keeping the same show but moving back half an hour, then he made some huge ordeal about it and it ended up pissing off a bunch of people who never watched his show to begin with. Its dumb and really baffles me that you cannot see that.
