US regulators have unveiled the nation’s first plan to give every American super-fast broadband by 2020.

The Federal Communications Commission (FCC), which will now submit the plan to Congress, said broadband was the “greatest infrastructure challenge”. It estimates that one-third of Americans, about 100 million people, are without broadband at home.

The FCC’s goal is to provide speeds of 100 megabits per second (Mbps), compared to an average 4Mbps now.

“Broadband for every American is not too ambitious a plan and it is absolutely necessary,” former FCC chairman Reed Hundt told BBC News.

“The consequences of not succeeding are heartbreaking. Every nation needs a common medium to gather around and to have the internet as a common medium where a third are left out is unacceptable.”

In an executive summary released ahead of the presentation to Congress on 16 March, the FCC said: “Broadband is a foundation for economic growth, job creation, global competitiveness and a better way of life.
