Rca left everyone else at the alter

[oldtvman]

I know that during the developement of color television all the ideas and principles that Rca used for its compatible color system were'nt theirs alone. I wonder if any of you old timers can shed more light on the fact that after the fcc adopted the never the same color system, most manufacturers then decided to let Rca sell color to the public, not to mention the bad taste CBS had for having their line secuential system thrown in the trash. any thoughts?
