No. FCC has not imposed new regulations but their lack of concern over administering existing law and seeing that cable companies abide by the wishes of Congress has resulted in cable operators now making it more difficult than ever to have the 'genuine outlet' Congress intended.
New rules were adopted Nov. 2007 but the cable industry succeeded in having the court 'stay' the rules and FCC has not taken any action to pursue opposing NCTA in court. As a result, the stay and a couple of outlandish orders so strongly in favor of cable to smell bad on behalf of FCC's Media Bureau has some cable sites denying LAPers (leased access operators) the use of IPTV technology to deliver signals. In fact FCC won't even answer basic questions regarding how cable is setting unwarranted conditions and terms on users and simply says 'file a complaint'.
It's amazing Congress has not realized FCC is basically looking the other way while cable operators ignore the law.
