       TIL: Early wireless TV remote controls (1956), commonly known as "clickers", didn't have batteries or electronics. When you clicked the button, an ultrasonic sound was emitted by the button striking the bar. This sound was picked up by the TV to operate it.https://en.wikipedia.org/wiki/Remote_control#til #todayilearnedhttps://www.reddit.com/r/todayilearned/comments/16iun1c/til_early_wireless_tv_remote_controls_1956/

       @todayilearned Back in the 1970s, I visited a family in Greece.  They had a remote control that was attached to the television via a thick black cable.  That's the only wired TV remote I've ever seen.

       @todayilearned I remember a friend's family had that. When the dog trotted through the room its jingling dog tags would make the channel change.
