30 Rock is coming back sooner than planned. It was supposed to be off the air for a little more than a month, but will return April 5 instead. That night will be a "super-sized" night on NBC (aka one of those nights you can't figure out when things start). After that, 30 Rock will move to 9:00.
The suits at NBC must be as addicted to Tina Fey as I am.
