Curious minds want to know.

Quick and dirty: There was a bunch of fiddling with the exact frequencies for experimental TV in this band until the original NTSC (monochrome) specs were agreed. FM radio was going to be there instead. Eventually, FM got moved to its present band and the channel 1 band got assigned to land mobile (I think both police and things like taxi dispatch).
