I realize that's not the same thing as coverage of zip codes. Unfortunately the report doesn't break out the number of non-satellite providers per zip code. But, it does break out the number of providers of different types reporting per state, and satellite provider numbers are either 0 or redacted across the board (because they're deanonymizingly low).
If you run numbers on the zipcode data for 2008 [1], 88% of US census tracts had 4+ providers, 75% had 5+ providers, and 60% had 6+ providers. It's just not plausible that satellite providers account for this.

In order for coverage and competition statistics to be useful, they need to keep up with modern bandwidth and latency requirements. IMO the absolute bare minimum that should be acceptable is 2mbit/s (for sub-SDTV video quality), with ping times less than 80ms. Meaningful participation in the modern digital world requires 15mbit/s or better, especially for households with more than one person.
