FCC chief says Comcast violated Internet rules

The potentially precedent-setting move stems from a complaint against Comcast Corp. that the company had blocked Internet traffic among users of a certain type of "file sharing" software that allows them to exchange large amounts of data.

"The commission has adopted a set of principles that protects consumers access to the Internet," FCC Chairman Kevin Martin told The Associated Press late Thursday. "We found that Comcast's actions in this instance violated our principles."

Martin said Comcast has "arbitrarily" blocked Internet access, regardless of the level of traffic, and failed to disclose to consumers that it was doing so.
