Best Answer

Most simplistically, it works on radio waves, invisible wave lengths that can be picked up by receivers and translated into electronic signals that control displays on a "picture tube".

Most recently, digital signals have replaced analog waves, and of course many people are now receiving the electronic TV digital signals via cable, rather than by air-waves.

TV's, unlike just a radio, need to have a video tube, and an electronic tuner to put "color" pixels onto a screen of some sorts (plasma, or LCD's are more common today, than old picture tubes)
