As you know RCA was once a huge & powerful corp. They
were famous for suing the crap out of any competition. Also
I have met several old RCA engineers that HATED them
because they invented things & got zero credit. The contract
stated all inventions were property of RCA BUT even the slightest
credit was not given. Others years after leaving RCA were sued
because they claimed they invented things while on RCA's time.
As far as CBS goes it may have been OK for a few years but
NTSC color was better & served us well for over 60 yrs........
