Very recently the United States Court of Appeals for the District of Columbia struck down the 2010 FCC order that imposed Net Neutrality on wireline broadband services.
What this means is that an ISP (Internet Service Provider) could slow down your connection to un-sponsored or un-preferred sites, picked by that specific ISP.
It could also allow them to completely deny service to certain services (IE: Gaming) unless you bought a package that allowed gaming.
