As might be expected, reactions to today’s speech from Federal Communications Commission Chairman Julius Genachowski are appearing, with feedback varying wildly depending on which side of the fence the comments come from.

Representative Edward J. Markey (D-MA), co-author of the Internet Freedom Preservation Act, praised Genachowski’s announcement, stating:

This is a significant step towards preserving the free and open nature that has enabled the Internet to become a platform for innovation, job-creation and economic growth. I hope the full Commission follows Chairman Genachowski’s lead in this vital effort.

PCMag has reaction from Senator Kay Bailey  (R-TX), who, it was noted, added an amendment to an Interior Appropriations bill that seeks to ban the FCC from spending funds to formulate and apply regulatory changes:

I am deeply concerned by the direction the FCC appears to be heading. These new regulatory mandates and restrictions could stifle investment incentives.

Comcast Executive Vice President David Cohen, whose company has battled with the FCC over network management policies in the past, took to his company’s blog to comment on today’s action:

We welcome the dialogue suggested by the Chairman in his comments, and we completely agree that any consideration of new “rules of the road” begin with notice and an open, public rulemaking proceeding – this is both fair and appropriate.

An article on CNET further details the initial reactions and stance of the wireless industry in regards to Genachowski’s comments. In a nutshell, some carriers, along with CTIA, the wireless industry’s trade association, do not want net neutrality laws extended to wireless service providers.
