I haven't mentioned it lately here but the Academy of Television Arts & Sciences Foundation's Archive of American Television continues to produce (and post to the web) important oral histories of the TV business.
They've just posted something I wish I had time to watch soon. It's a four hour (four hour!) interview with Don Pardo. Don is best known as the announcer on Saturday Night Live (and before that on the original Jeopardy!) but he's been a professional for over sixty years, doing just about every kind of show on which one can announce. That has to be a fascinating conversation.
