Viacom pulled their channels from DirecTV early this morning, after a long dispute over how much the satellite company would pay for Viacom programming.
No Viacom means no MTV (Snooki!), no Comedy Central (Jon Stewart!), and no Nickelodeon (Spongebob!).
Other missing channels include BET, CMT, TV Land, Spike, and Logo. For now, Viacom has replaced the channels with channels offering similar content.
About 20 million households are affected by the blackout.
These feuds aren't unusual, but they are often worked out at the last minute. The New York Times story linked above says that Michael Nathanson, a media analyst for Nomura, has told investors that he and his colleagues wouldn't be surprised if the blackout lasted for one to four weeks. Yikes.
