Yesterday's video link was, as I mentioned, a kinescope. Just as folks were writing to ask me what the heck a "kinescope" is, my buddy Jerry Beck dropped me a note to tell me about this wonderful short film from 1949 that explains about the process with examples. I think the footage of Arturo Toscanini conducting the NBC Symphony Orchestra was done in Studio 8H in Rockefeller Center, which is where they now do Saturday Night Live.
