I had a small portable BW TV that was about the size of a modern smartphone. It had a mirror that you flipped up that reflected the screen. It ran on 2 or 3 AAA batteries. It was great!

Digital TV killed great broadcast TV. Once the bandwidth was sold small devices like this became paperweights.

I also liked watching Black and Whit TV because my brain would forget I was watching black and white.

I hate TV now. I just watch youtube or other specific videos on interesting subjects.
