Broadband Internet is becoming the country’s primary telecommunications medium, and the FCC wants to widen it. The big corporations, of course, will fight this to the death, and warn us that it will cause the universe to explode and turn your neighbors into brain-eating zombies.

The Federal Communications Commission is proposing an ambitious 10-year plan that will reimagine the nation’s media and technology priorities by establishing high-speed Internet as the country’s dominant communication network.

The plan, which will be submitted to Congress on Tuesday, is likely to generate debate in Washington and a lobbying battle among the telecommunication giants, which over time may face new competition for customers. Already, the broadcast television industry is resisting a proposal to give back spectrum the government wants to use for future mobile service.

The blueprint reflects the government’s view that broadband Internet is becoming the common medium of the United States, gradually displacing the telephone and broadcast television industries. It also signals a shift at the F.C.C., which under the administration of President George W. Bush gained more attention for policing indecency on the television airwaves than for promoting Internet access.
