I had a TV with an ultrasonic remote. It was a nightmare. Whenever I moved the curtains, random things happened with the TV, including the volume hitting a 10 in the middle of the night...

maybe still better than the flashlight/photocell types!

And that's where the term "clicker" came from, as opposed to the more modern "remote".

I had one of these TVs when I was a kid, it came from my grandparents' house when they got a new one. We also had a dog that wore a steel-linked choker collar, and the TV channels would change, or the TV would turn on an off when he ran around and jangled the collar.

This is why remotes are sometimes called "Clickers"

When my friend’s dog would run across the living room the tags on its collar would jingle and change the channel. Sometimes at a very important part of a program we were watching! 🤣
