This afternoon, I was informed that @POTUS @realDonaldTrump designated me the 34th Chairman of the @FCC. It is a deeply humbling honor. pic.twitter.com/Joza18aP33 — Ajit Pai (@AjitPaiFCC) January 23, 2017

That letter made it clear that pro-consumer practices that made life tougher for businesses are going to be under scrutiny. Net neutrality rules that prevent things like pay-for-priority access, blocking and throttling are "unjustified burdens" for service providers that the FCC now intends to do away with. How quickly this will come to pass remains to be seen, however -- it may take months of hearings, procedure, and public comment before the rules of the land can be changed.

Pai can stay on through 2017 as FCC chairman, after which he'll need to be reconfirmed by the Senate -- something that seems likely with Republicans in control.
