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.

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.

The idea that you waited for that particular issue to come out, but then you planned your TV viewing for the coming season, it was a completely different world. And I grew up in Fort Lauderdale, so there was a TV critic writing for the Miami Herald, Jack Anderson, that was very influential. Just to read, every morning, somebody who cared about TV as much as I did - they were an adult, and they were clearly being paid for it. That was an "a ha!" moment for me before I was even 10.

I keep writing books about why TV is good. There's nothing more fun to me than steering people toward something that I really loved that I think they might not otherwise see. That's the reason I do what I do.

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.

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.
