The net neutrality regulations adopted Thursday by the Federal Communications Commission prohibit providers such as AT&T, Comcast and Verizon from selectively speeding up, slowing down or blocking users’ internet traffic.

The latest rules show how, with a 3-2 Democratic majority, the FCC is moving to reassert its authority over an industry that powers the modern digital economy, touching everything from education to health care and enabling advanced technologies such as artificial intelligence.

The vote marks the latest twist in a years-long battle between regulators on the one hand, who say consumer protections are needed to ensure all websites are treated equally, and ISPs on the other who describe the rules as heavy-handed government intervention.

Whether it is throttling content, junk or hidden fees, arbitrary pricing, deceptive advertising or unreliable service, broadband providers have proven over the years that without proper oversight, they will not hesitate to use their power to increase profits at the expense of consumers.”

In past legal battles over net neutrality, courts have deferred to the FCC, ruling that it has wide latitude to regulate ISPs as it sees fit using the authority it derives from the agency’s congressional charter, the Communications Act of 1934.
