The pdf version is not correct. ( that's the govt' for ya!) It shows TV allocations in VHF, among other errors. It's not all that informational either. I looked to see what was above the 20m ham band and there's a slot that says fixed/mobile. For what entity?
Well, at least it's colorful if not useful...
While HDTV happened a few years ago I think that the allocations have not officially changed yet. There are a "few" stations that successfully petitioned to keep their VHF frequencies under the claim that by moving to UHF would hinder their ability to cover very large service areas. That argument has come up many times in the past. If you are interested you should do some digging on what the VHF channel allocations did in the 1950's (including what happened to channel 1).
That is why they are calling some of these new technologies as "white space" devices. They are supposed to be intelligent enough to select frequencies that are not being used by commercial broadcasters that may still be active in some markets. When those devices hit the market they will probably show up as secondary allocations in portions of the television broadcast bands.
If the FCC had the courage to actually make some decisions they could just mandate that the VHF spectrum; 54-72 MHz (18 MHz wide), 76-88 MHz (12 MHz wide ), 174-216 MHz (42 MHz wide) would be vacated with broadcasters moving up to the UHF spectrum. That would free up 72 MHz of spectrum in some pretty valuable portions of the band for public-safety, commercial land-mobile users. That would allow for the creation of 5,600 7.5 KHz wide channels or a mix with higher bandwidth spread spectrum data channels. That should resolve the entire spectrum debate of land-mobile for quite a while.
The reality is that the FCC is not a regulatory agency but more of a political action group for commercial interests (like how the FAA is the same thing for airlines). Can we have 69.9 to 70.6 MHz for a 4 meter band, pretty please?
The spectrum chart is indeed outdated. Most certainly there are many other errors on the chart that we are just not aware of. Our secondary allocations on 60 meters are not shown. Hopefully we will see something about 600 meters in the next few months (yea, and if wishes were horses, beggars would ride
