Lot of stuff about Bob Trachinger on the Internet...

Really hoping that people here recognize the names of the chief engineers and cameramen.

Or any of those people are members here...

Thanks for the first two links...

Were these advertisements from a series of commercials done by RCA in which they interviewed technicians on the production sets of NBC shows, where people praised the performance of RCA equipment?

Mad Magazine ripped them to bits.
"THE PART THEY LEFT OUT: Note how all these technicians are with NBZ. That's because NBZ is OWNED by RZA, so what would you expect them to use?"

RCA had around 40% consumer TV market share back then.... By percentage market share they could probably find enough people in the TV broadcast industry that own and like their RCA in the state of Ri to make that commercial and ignore the 40% that own Zenith and the 20% that own something else...

Hell they probably could probably try to claim that "most dentists and or most blind people choose RCA as their TV"....
