I heard someone on the radio today refer to radio as terrestrial radio (as opposed to internet "radio"). A quick Google search reveals that this inaccurate term has become fairly standard. Now internet "radio" is not radio but simply music selected by someone else to listen to coming via another medium. People do that over radio waves too, and they just wanted to capture the feel of radio stations but in a different medium. I could understand internet television, since that term is not tied to the medium the signal is carried in. But the word 'radio' is, or at least it used to be before whoever started talking about internet "radio" hijacked the term.
It's always seemed a bad idea to me to call that radio, but I think it's worse to refer to actual radio as terrestrial radio. Something is terrestrial if it is on the ground. Radio waves go through the air. What's worse, however, is that internet "radio" is much closer to the ground than actual radio. Internet cables can run through the air but can also run along the ground or underground. It would thus be much more accurate to call radio by its name, 'radio', and to refer to this thing they're calling internet "radio" as terrestrial radio. It wouldn't be accurate, but it would be more accurate than what they're using the term for now. But I guess people who coin words don't often think about what they're doing, and we've now got a case where terrestrial radio is not terrestrial, and internet radio is not radio. At least they're not distinguishing between AM and FM internet radio.
