    Hey, man. What a great question, seriously. Maybe the higher the number, the younger the channel in age? like channel 7 was created before channel 20 maybe? Just a guess, this is going on my watch list :)

    They originally named them after the frequency I think they went from 52 to 980mgh.

    Above that was uhf.

    FM channels went from 88 to 108 I believe. They do have lower than 52 but I believe this was for return channels.

    The new digital TV may have changed a lot of this.

    Thirty years ago I could have told you a lot more .

    I hope this helps.
