The word "stereophonic" comes from Greek stereos = "solid" and phōnē = "sound". It was coined by Western Electric.

In popular usage, stereo usually means two-channel sound recording and sound reproduction using data from two speakers. The electronic device for playing back stereo sound is often called "a stereo".
