In 1956, the first television remote controller was entered the American Home. As far back as 1893, a remote control for television was described by Nikola Tesla in U.S. Patent 613809.
The first wireless remote, designed by Zenith's Eugene Polley, is essentially a flashlight. When Zenith discovers that direct sunlight also can change channels on the remote-receptive TVs, the company comes out with a model that uses ultrasound; it lasts into the 1980s, to the chagrin of many a family dog. The industry then switches to infrared.
