Zworykin on live TV 1948 Eye Witness The Story of Television

Here's a link to an interesting kinescope of a live TV show on NBC's WNBT New York station in 1948, hosted by Ben Grauer. It was called "Eye Witness The Story of Television." It's a little corny at how simplistic it shows the history of TV development, but Dr. Zworykin appears at the end showing his early experimental tubes and films from the early 30's of them in action. Pretty rare stuff.
