TIMOTHY KARR: In the past 24 hours Comcast has been exposed committing blatant abuses of its power over all things media. The New York Times reported last night that the cable giant has threatened to block access to the popular online movie service Netflix unless the company that streams its films pays new and extortionate tolls. Earlier in the day, Comcast was caught red-handed trying to smother the marketplace for competitive Internet modems designed for use on its network — a violation of fundamental Net Neutrality principles that allow you to choose what devices you want to use. These are just the latest in a history of abuse by a company determined to become the 21st century’s media gatekeeper. If Comcast gets away with these violations, it will be the beginning of the end of the experiment in information democracy called the Internet. What more reason does the Federal Communications Commission need to step up — for once — and protect the openness that is central to a better, more participatory and diverse media. Taken as a whole, these abuses show us what a media monopoly looks like in the Internet age — one company, consolidating its media power to squash competitors, to stifle innovation and free speech, and to gouge consumers.
