Here is a site where you will find video interviews (2-4 hours long in 1/2 hour segments) with many of the greats behind and in-front of the camera. Scroll down the right side. I've looked at interviews with John Frankenheimer, John Moffitt, Vince Calandra and Heino Ripp. They all contain great stuff about the old days at CBS. If you take them a bit at a time you will find them very rewarding. Frankenheimer started at CBS, Moffit directed and AD'd Sullivan, Calandra was a PA & talent co-ordinator on Sullivan and went on to produce talk/variety shows and Ripp was NBC's first TD and worked every great show from Como thru Saturday Night Live.
