The map cost about $200 million (provided by the National Recovery Act of 2009), and offers a database of over 25 million documents showing the type, speed, provider, and location of broadband service. The most obvious way to use the map is simply to search for an address or zip code, and then narrow down results by type of broadband. Then you can see the maximum advertised speed of broadband, if it's available, which theoretically could be of use to businesses (they might not want to move to a location without reliable internet access) and consumers (ditto).
