The one thing that surprised me was personal: when he does his professional work and curating and lecturing, he does so by the more high-end Walter J. Podrazik." But here he's identified as just good ol' Wally. I asked him about that, and he said that C-SPAN told him that they'd worked with him for so long at the Democratic conventions that they felt it didn't seem right to call him anything but "Wally."
Wally is a very good guy, and it's an interesting, informative half hour. The early few minutes are a bit technical as he gets into the very beginnings of television, but it soon moves on. He's always been well-mannered and detailed in how he presents himself, but boy howdy, does he know his stuff.
Anyway, after my various mentions of the good fellow, here's the video of Wally, in glorious living color. And if you're interested in his book, Watching TV, you can find it this link at Amazon.
Unfortunately, C-SPAN doesn't provide a code for embedding their videos. But you can watch the talk about TV past and where it's going here.
