Ok my sister worked as an engineer for a large company (very large) in the 60's that didn't want to include FM tuners in their broadcast equiment.
What "broadcast equipment" has tuners of any kind in it?
(I suppose a frequency agile mod monitor is in a sense a tuner, but mod monitors are one band only.)
I am not going to say who the company was but they were often refered to by three letters, they later went chapter 11 in 1986 and was bought out by another big corporation that is still using their name today.
Via a process of elimination, that would seem to be RCA, a brand now owned by Thompson who also has the Philipps home electronics brand in its family.
This seems to indicate that you are not talking about broadcast equipment (see
http://www.davidgleason.com/Archive Miscellaneous/RCA Audio 1968.pdf for an example of RCA Broadcast equipment) but about consumer electronics of the sort one would have bought in Sears or J.C. Penney in the 70's... TV sets, radios, record players and cassette decks, etc.
In the consumer electronics area of radios and receivers, RCA faded long ago. But the driving force was the consumer, and if there was consumer interest in having FM along with AM, it did not take a government edict to make manufacturers offer that option. It just made good business sense.
The year of the FM simulcast prohibition, 1967, found RCA selling an AM FM radio for $24.95... it sure does not seem that RCA resisted putting out and promoting dual band products. RCA stopped making radios in the US in 1974, and closed the Indianapolis facility that made them... the last models offered actually were Japanese designs.
RCA never went into receivership. RCA, including NBC, was bought by GE in 1986, and the consumer lines of RC were sold to Thompson in 1988.
RCA made an FM receiver in 1946, but used a circuit it did not have to license from Maj. Armstong due to the quarrel between Sarnoff and the Major (who had been RCA's biggest shareholder at one time). In the mid-50's, there were a variety of RCA table radios, and I owned an RCA portable (when portables were still often plug-in models) in about 1960 when I had been working at an FM station. So RCA did incorporate FM in its product line, going back to the time the band moved from 46 mHz to the current location.
What RCA vehemently disliked was making FM devices that used Armstrong's patents. And, as long as they did not violate the patented inventions of Major Armstrong, they could do whatever they wanted... You may have mistaken a discussion of the patent issue for one regarding FM in general... RCA was one of the first manufacturers of FM gear after the War, and many of us, regrettably, have worked on the later vintage FM rigs. Fortunately, they stopped building them.
