The Zenith Lazy Bones of 1950 was the first commercially successful TV remote control. Plugged into the TV via its long wire it had two buttons on the top for tuning and volume.

At $30 extra (on top of a Zenith TV) this was not a cheap gimmick and at least the name and publicising was quite up front about the way TV remotes would come to dictate our TV habits in the future. The product seemed to sell well at the time, but complaints were made about the annoying trailing wire.

By 1955 this problem would become a thing of the past when their new entirely remote TV controllers were released.
