technically...it was CBS..however, it's the RCA system that was euventually adopted by the FCC.
CBS developed a color system that used a sequential field color system...to break it down..there was a rotating disc that contained three colors in front of a monochrome (black and white) camera, and it spun pretty fast...now..at the other end..you had a black and white TV with a similar disc spinning at the same rate (it was kept in sync using the tv signal)
believe it or not, CBS was expermenting with this was far back as 1939...before the NTSC had adopted the first standard for black and white TV..and actually tried to get the FCC to adopt it...but they had no interest.
in 1941, NTSC set a standard for black and white television broadcasts..TV's still weren't really mass market items at this time...but, most transmissions were still exparmental and used different formats...but even prior to this, CBS was test broadcasting color signals.
ok, so if CBS did it first...why didn't they get picked standard...well, the FCC wasn't really interested in color TV till 1949 when they called a hearing to discuss the issue. it was at this time that RCA stepped in with it's three dot phosphor system that required very little modification to the black and white NTSC signal...my source doesn't say when RCA actually statrted developing and testing thier system...only that they came public with it and were doing test broadcasts in 1949.
the CBS system, with it's higher scan rates and the fact it's cramming more fields into each frame because of that spinning disc had a lower quality black and white signal...pretty much making it incompatable with NTSC black and white tv's that were out at the time. you'd either need a dual-mode set or a seperate color unit...whcih, actually, the first and only commercially released tv using the CBS color system, was released in 1950 and had a switch to select between color and black and white mode.
but the RCA system, while it modified a few aspects of the transmission...left the black and white portion of the signal untouched....color units would be able to pick up the color information and recreate a color picture, while black and white tv's would only see the basic brightness signal and produce a standard black and white TV....in fact, an NTSC tv from 1941, if working, could be hooked up and used today while analog transmission is still around.
it was mostly because of compatibality issues that the RCA system was adopted by the FCC in 1953, with color broadcasting starting offically on jan 1, 1954.
...actually, that's just the gist of it...it's a long and complicated timeline of events on both sides..lawsuits...fcc rulings....however, everything you could ever have wanted to know about color tv, is over here:

The RCA CT-100 color Tv was introduced in March 1954.
Obviously RCA rolled them out first.
It was pretty shabby color to say the least, but at the time I would imagine it was hot stuff.

I enjoyed my C64 to dying! I consistently used an previous RF adapter that screwed onto the back of a television. you could desire to have the means to apply some RF cables, besides. in case you have any wisdom of electonics, you could desire to have the means to go on your community Radio Shack and positioned something together. If no longer, take your C64 down there and that they could make it easier to. solid luck!
