Internet companies are readying for a showdown with telecoms and a Republican-controlled government over a policy near and dear to their hearts: Net neutrality.

Net neutrality basically prevents broadband providers from playing favorites or steering users toward (or away from) particular internet sites. Under rules enacted during the Obama administration, the likes of Comcast and Verizon — which offer their own video services they'd very much like subscribers to use — can't slow down Netflix, can't block YouTube, and can't charge Spotify extra to stream faster than Pandora.
