This map uses FCC data to show you how many internet service providers you have where you live (or any address you search for). Users can also search for any address in the United States.
If you would like to read more about how I built this map, check out a blog post I wrote for Mapbox's blog detailing the process I used to obtain, process, and render the data that went into making this map.
The FCC has since disabled the API that allowed the application to pull detailed information about the providers available in a given census block. The application still works and provides the user with the ability to see how many providers are available in their block, but the detailed information is no longer available.
