I got into television criticism because I thought it would be easier than film criticism. Film, you had to know 100 years of history, and TV you only had to know 40 when I started. And I thought, "Well, that's going to be so much easier." But film stayed pretty much the same. And television has changed so many times that my head hurts. So I made the wrong call there.

I wrote my own first book about the defense of television as an art form in 1992. It was harder to make the argument then. Now it seems absolutely a given. You can argue about when the Platinum Age Of Television begins, but I don't think that anybody can argue that it's not here.

I'm such an old fart that I started buying books on film and TV and radio and music when, for television, the entire shelf of books was only a couple of them. You go into the '70s before you start getting books on TV that you start wanting to collect. And by the time that you get to something like the Brooks and Marsh book it's invaluable. My house got hit by lightning in 1989 and burned down. And I got more than a half dozen Brooks and Marsh books sent to me by friends immediately, as though that's what you need more than clothes or food. That's how treasured that book was.

"Transparent" is a drama slash comedy series that could, in theory, make the Emmy nominations next year in either of those categories - it's that good.

I would not even attempt to do a history of world television. I did a half dozen years where I was a juror at the Banff World Media Festival, and you get the best TV in the world there, and I was astounded at my ignorance. I would be watching a documentary made in Japan, and it was astounding, and I would never have heard of that otherwise. We're seeing more and more imports in the last years, and my dream for the next generation of TV is that somehow we get to tap into all of that.

Downton Abbey is the most popular drama in the history of public television. When the whole of the TV universe is fragmenting, that isn't just impressive. It's almost impossible. But here we are.

Even though I'm a writer and I love books and writing books is my favorite thing to do, when you teach, and you can go through the history of children's television, and I show certain things, the students' jaws just drop. You're never going to hit the hammer quite as hard in print.
