I still remember my first remote control; at least, the first one to come under my control. It belonged to my Mama Ruth and Papa Solly. It had two buttons, one for channel and one for volume. Both worked only in one direction, from bottom to top; the channels ran in an endless loop; the volume shut the TV off before it went back to soft.
They soon grew more sophisticated and numerous; now everything above a transistor radio comes with one, and coffee tables are littered with them.
