[EDIT- Correcting myself - 5 MW analog is correct - I really did not recall that.] Have to check, but I don't think I've heard of a 5 MW analog station - I think the limit was 1 or 2 MW.
Current limit for high UHF digital is 1 MW, but that can be restricted on the east coast where geographic packing is tighter.
VHF digital is a problem with low allowed ERPs because the FCC planning software did not take ambient noise into account correctly. VHF is also a problem because if you do turn up the power, you get enough over-horizon propagation to cause interference to other VHF stations on the same channel.
