You might be surprised at how common that was. Many people had console TV's, some the still worked but were black and white and everyone else had color TV's. They were expensive when they first came out so you bought a smaller color set and just put it on top of the console. It is also possible that the old ones just didn't work anymore.
My parents had a massive console. It had a built in AM/FM radio (also a new thing at the time) and a turntable record player and Black and White TV, however, it was a beautiful piece of furniture. My mother couldn't let it go. I think it was the nicest piece of furniture they ever owned and she didn't want to just throw it away. It eventually ended up out in the porch and just held a lot of minor decorative things. For years it just sat there taking up room, but she wouldn't part with it. After she passed, we reluctantly took it to the old appliance grave yard still working and still in pristine condition.
