Just changed a line in the piece below about Mr. Rogers. I originally wrote he was on TV for 22 years. Actually, I meant to write that his best-known series was on for 22 years, which is what some obits say — but it turns out that's not accurate, either. Fred Rogers did his first TV shows around '51 or '52 and did his last episode in 2001 — an amazing achievement. Thanks to Mark Thorson for keeping me honest.
