I thought Regis had just decided to retire, but I saw him admit to Katie Couric that it was a dispute over his salary. He said they didn't want to pay him what he thought he was worth. I also read what they were paying him and it was some obscene number. He was good, but not that good. It was in the high millions. In my wildest dream, I would never imagine that he could earn that much money per year. It really boggled my mind that he would leave his show over money, when you know he has enough money for he and his entire family to live VERY comfortably for the rest of their lives. It really turned me off. Here's link:
