The problem is that huge parts of those shows don't exist. Many were shot on kinescope and have not survived the years.

>What I'd really like to see (and I haven't checked availablity) are some of the really old interesting shows - Edward R. Murrow, You are There. I'd love to pick up the complete Sid Caesar's 'Your Show of Shows', but afaik it's never been released - just small collections.
