California's law, which prohibits internet service providers from slowing down or blocking access to websites or charging companies like Netflix extra to deliver their services faster, is based on Obama-era net neutrality protections that the Republican-led FCC rolled back earlier this year. But California's law goes further, also outlawing some zero-rating offers, such as AT&T's offer, which exempts its own streaming services from its wireless customers' data caps. The law also applies the net neutrality rules to so-called "interconnection" deals between network operators, something the FCC's 2015 rules didn't explicitly do.

The law, which had been signed by Gov. Jerry Brown in September, was supposed to take effect on January. The Justice Department filed suit against California almost immediately.
