With the East Coast ravaged by Hurricane Sandy, Nielsen just put up a note that ratings for last night are delayed until around 1 PM ET due to impact from the storm. Only NBC and ABC aired their lineups in originals last night, with CBS and the CW switching to reruns and Fox already slated for repeats because of its World Series coverage. Ratings will likely be impacted by the storm, which caused massive evacuations and power outages. By the beginning of primetime on the East Coast, more than 2 million were without power. That number has now climbed to 7.5 million.
