My wife and I bought an RCA color TV back in 1965. The first game broadcast in color was Thanksgiving Day, from Detroit. The Packers were not in that game. Lombardi had killed their involvement in it. He hated it.
The following year, games were broadcast in color. It was a treat watching them, after seeing b&w for so many years.
I can remember, on network TV, shows that were in color, even if they were horrible, had an edge in viewers, as people with color TVs chose color over content. Sadly, my wife and I were among them, at times.
I remember when an NBC show was about to come on, in color, they'd show a picture of the peacock, with it's colors. "Brought to you in living color, by NBC!"
That first color TV was a 21" round tube, and it was a console. It must have weighed at least 350#. If you moved it, the "guns," which were the red, blue, green guns of light that created the picture, would get out of alignment, and have to be realigned. They were monsters, but if you owned one, people loved coming to visit, to just watch a TV show they liked.
On Packer days, I had 3, sometimes 4 friends and their wives, who came over every Sunday, to watch the games. We'd get a pony of beer, and drink the whole thing, over the course of pregame, game, and post game shows. The women helped some, but it was mostly us guys. We'd split the cost, and each wife would prepare something and bring it to eat.
I'm sad to say that only one of those old friends is still alive, and I haven't actually seen him in over 25 years. But, back in the day, we had one helluva good time on Sundays, as Packer fans.
