电视机

Why does 电视机 look like this?

电 (Electricity) + 视 (To look/view) + 机 (Machine). Together, it literally means 'electric viewing machine'. The radical for 电 is the rain (雨) variant (though simplified), 视 contains the eye (目) and show (示) radicals, and 机 has the wood (木) radical suggesting it was originally a wooden mechanical structure.
