Consumer advocacy group Public Knowledge recently filed a petition with the Federal Communications Commission (“FCC”) challenging a multi-system operator’s (“MSO”) online video service as violative of conditions imposed as part of a 2011 merger and the agency’s Open Internet rules. The service allows the MSO’s customers to stream its licensed video content to computers, tablets, and mobile devices without incurring additional data usage charges.  The MSO maintains the content of this service does not touch the public Internet – and thus is not subject to the Open Internet rules – because it is delivered on the same private, managed network as its cable services.
