What IS different is that in FM and TV, the tx power has to be set with 
respect to the antenna system gain, to produce a licensed ERP in the 
horizontal plane.   As Peter Haas noted, AM ERPs in the horizontal plane can 
vary by up to ~2:1 for omni stations with same tx power, depending on their 
antenna 'efficiency.'
