  • 1956 - Dr. Robert Adler, an engineer with Zenith Radio Corporation / Zenith Electronics Corporation, files a patent for the first practical wireless television remote control. The device, marketed as the “Zenith Space Command,” used ultrasonics (high-frequency sound) to transmit channel up/down and power on/off signals. The device was a precursor to the other types of environmental control units used today. [1] [2]
