“People need to understand that’s what we’re debating here.”

The debate revolves around net neutrality, which in the broadest sense holds that Internet users should have equal access to all types of information online, and that companies offering Internet service should not be able to give priority to some sources or types of content.

In other words, on mobile phones or on special access lanes, carriers like Verizon and AT&T could charge content companies a toll for faster access to customers or, some analysts worry, block certain services from reaching customers altogether.
