For a given transmitter, does there exist a limit on the number of recievers?

For example, does the wattage of a radio station affect the number of available listeners? I would think that if I tune my radio to a particular radio station, I am removing energy from the electromagnetic field created by the radio antenna.

Not in any meaningful way.

A radio will physically block the propagation of a small part of the signal...but not any differently than a toaster would.  And it would not matter what station it was tuned to, or whether it was even turned on.
