Well.....like it or not......that's what the entire world calls it. It's called internet radio. It's NOT AM radio, it's NOT FM radio and nobody said it was. While it's true that it's NOT radio in the traditional sense, but neither is satellite radio, yet it's also called radio.
At least satellite radio is a lot closer to OTA radio than internet radio.
Anyone who thinks that AM radio will be half what it is today, 25 years from now is living in a fantasy world. It may still exist, but it won't even be a major player 25 years from now.
I think many would be excited at the prospect of AM at least being half what it is today, 25 years from now, as an 88-year-old Rush Limbaugh tells his listeners what's wrong with liberals. His audience by then of course will have nobody under 72.
