"European Commissioner Thierry Breton, who is responsible for the EU internal market covering more than 450 million people, spoke to Netflix (NFLX) CEO Reed Hastings on Wednesday and again on Thursday about the strain video streaming was placing on networks."
Apparently the EU thinks it's a problem.
The truth is that this will probably make little difference, but it makes sense for Netflix to do this since it doesn't cost them anything and now they are owed a favor by a regulator.
Also it would be the first time that a U.S net company does something voluntarily just by kindly asking.
