my guess is that the 109 Mhz portion of the original modern FM Band was reallocated by the FCC to either the police or the Military (just like everything else was that the FCC didn't think we needed anymore including the old Analog TV broadcast spectrum, I'm kind of seeing a pattern here...

The entire FM broadcast band is between TV channels 6&7, plus the aircraft band. The old FM band, 42-50mhz is around the low band TV channels.
I'd have to read up again to be real exact.

Yeah, I'm not sure either all I know is that the reason why FM was created in the first place was because the FCC got rid of Channel 1 with Analog TV shortly before we entered WWII so then because of that then the 42-50 Mhz FM Broadcast Spectrum came into being, but then the FCC thought that the military could make better use of the 42-50 Mhz spectrum better which was when they decided to open the modern 88-108 Mhz FM band just shortly after WWII (but I wasn't aware of it being originally 88-109 and from when to when that was I don't know.)
