It's not quite that simple (though it's what I thought as well...)
Here's what looks like a comprehensive story:
http://www.tech-notes.tv/History&Trivia/Channel%20One/Channel_1.htm
The short version: The FCC got it wrong about how far the signals would
propagate, and when interference became a problem between stations that were
over the horizon from each other, things had to change. So the TV industry gave

technology and politics.
Note that channels 1 and 2 moved around quite a bit in the 30's and 40's.
Things settled down in 1948.

of view) that you might want ....
