That number could be either high or low, compared to what we need:

- Does it include cable/satellite stations (CNN, Sci-Fi, HBO, etc.)? If
  not, the number could be low, although probably by less than 10%.

- What precisely is a "licensed TV-band transmitter"? I'm guessing
  this definition includes more than the TV stations for which we'd want
  to provide data. I say this because there are 210 DMAs (TV markets) in
  the US, and 8839/210 = 42.09. There certainly aren't an average of
  42 OTA TV stations in each DMA.

Overall, I think 8839 is a high estimate. Assuming a dozen stations per DMA 
and 500 cable/satellite stations, that works out to 3020 stations. My guess 
is this would be a high estimate, but I doubt if the number would be less 
than half that.
