A few bits I dug from this good mini-profile of Jon Stewart:

Instead, he describes his decision to quit The Daily Show, the American satirical news programme he has hosted for 16 years, as something closer to the end of a long-term relationship. “It’s not like I thought the show wasn’t working any more, or that I didn’t know how to do it. It was more, ‘Yup, it’s working. But I’m not getting the same satisfaction.’” He slaps his hands on his desk, conclusively.

“These things are cyclical. You have moments of dissatisfaction, and then you come out of it and it’s OK. But the cycles become longer and maybe more entrenched, and that’s when you realise, ‘OK, I’m on the back side of it now.’”

...

Like every TV celebrity, in person, Stewart is both better-looking than you expect and smaller, with his long torso making up most of his 5ft 7in, giving the illusion of height from behind his studio desk. He is dressed casually, and after years of watching him on TV wearing a suit, seeing him in a T-shirt and casual trousers feels almost like catching my father half-undressed.

...

Now that he is leaving The Daily Show, is there any circumstance in which he would watch Fox News again? He takes a few seconds to ponder the question. “Umm… All right, let’s say that it’s a nuclear winter, and I have been wandering, and there appears to be a flickering light through what appears to be a radioactive cloud and I think that light might be a food source that could help my family. I might glance at it for a moment until I realise, that’s Fox News, and then I shut it off. That’s the circumstance.”
