when did tv's first have remote controls?
1940
the original television remote control was a wired version, released in 1950, that soon attracted complaints about an unsightly length of cable from the viewer's chair to the television receiver. eugene f. mcdonald, zenith president and founder, ordered his engineers to develop a wireless version, but the use of radio waves was soon discounted due to poor interference rejection inherent in 1950s radio receivers. the 1955 flash-matic remote system, invented by eugene polley, used a highly directional photo flash tube in the hand held unit that was aimed at sensitive photoreceivers in the four front corners of the television cabinet. however, bright sunlight falling on the television was found to activate the controls. it is worth noting that these remote controls would activate a motor, causing the tuning dial on the television to switch by itself, and this could be used for mischief if someone else was attempting to tune the television.

remote controls in military usage employ jamming and countermeasures against jamming. jammers are used to disable or sabotage the enemy's use of remote controls. the distances for military remote controls also tend to be much longer, up to intercontinental distance satellite-linked remote controls used by the u.s. for their unmanned airplanes (drones) in afghanistan, iraq, and pakistan. remote controls are used by insurgents in iraq and afghanistan to attack coalition and government troops with roadside improvised explosive devices, and terrorists in iraq are reported in the media to use modified tv remote controls to detonate bombs.
