I always heard in those days there was a lot more cooperation on the engineering side of things than there was at corporate. Might not have been unusual for someone from RCA to unofficially pop in at CBS and see how things were going. A lot of them probably knew each other.

I had an uncle who worked for ABC Sports as a sound engineer. He started about 1950doing golf. He used to talk about how ABC had to borrow almost all of their remote equipment from NBC and got a lot of help from them. Everything had NBC painted on it and people used to walk past and think they were NBC employees.

He used to say ABC wouldn't have been on the air in those early years if it wasn't for all the stuff they borrowed from NBC. At that time ABC wasn't far removed from being the NBC Blue network, so there was probably a lot of people who knew each other.

He's been gone many years now and I really wish I had talked to him more about those days and recorded it someway.
