Right. I have the three dvd sets of CBS’ “Suspense” tv-series (1949-54), which is comprised of nearly a hundred kinescope episodes, from those “live” seasons. They were believed lost for decades. I also have the two “Mr. Peepers” (1952-55) dvd-sets, also entirely comprised of kinescope prints. The game-show network used to run kinescopes of those panel-shows like “I’ve Got a Secret” and “What’s My Line.”
Unfortunately, a lot of kinescopes eventually got junked, too, rendering the shows “lost” to the ages. Not too many episodes of things like “Meet Millie” or “My Friend Irma” seem to have survived, for example.
And the local shows ( those only shown in certain areas ) are also very much long gone; sadly. :-(
