Comcast Corporation state-reach reading

Comcast Corporation opens on geographic reach: #5 of 2,138 filers by states with filings (40 states), with 1,694,032 records behind that footprint.

Among 2,138 Form 477 providers on this site, Comcast Corporation sits in the upper third by record volume (≥ 2,064). Large books usually mean many census blocks marked served, not that every block has active subscribers.

Comcast Corporation's filings are geographically dispersed; even the lead state (Pennsylvania) is only 10.4% of the book (176,756 records). Form 477 historically let providers mark a whole census block from a single reachable address; treat these counts as declared capability, not address-level availability, speed, or price.
