We scoured the internet, public data sources, and private proprietary databases for all of our information.
In short, the answer is from a ton of government sources. In general, data from the following government entities was useful: Bureau of Labor and Statistics, Federal Communications Commission (FCC) and the National Telecommunications and Information Administration (NTIA). But we supplemented and fact-checked all government data with countless hours of research into the providers themselves.
Also, for our TV research, we used data from Nielson, Inc. and NetFlix, Inc.
