What were you watching on TV Monday night? If you were watching original content, the odds are you were watching "Dancing with the Stars", "The Voice" or Megastorm Sandy Coverage!

Scores of primetime shows did not air as originally intended Monday night. Instead, networks including CBS, ABC, NBC and the CW ran re-runs, choosing to hold off new episodes until next week when more viewers are hopefully able to tune in. CBS confirmed to The Hollywood Reporter that last night's intended lineup of originals will air next week instead. That includes new episodes of "How I Met Your Mother", "Partners", "2 Broke Girls", "Mike & Molly" and "Hawaii Five-0", many of which were Halloween-themed episodes. Apparently Halloween will last two weeks this year, at least on TV! 

CW's new episodes of "90210" and "Gossip Girl" will also be delayed until next Monday.

Networks who did go ahead with primetime originals, NBC and ABC, earned the night's highest ratings, according to The Hollywood Reporter. "The Voice" was up 16 percent from the last original episode. "Dancing With the Stars", also a new episode, and two hours long was up among adults 18-49. Overall, ABC topped among viewers with 2.7 million tuning in.

Monday night, CNN reported that 6.5 million Americans were without power, a staggering number, in states from North Carolina up the eastern seaboard as far north as Maine. In New York City alone, hundreds of thousands were without electricity, leaving TV sets dark and late night television shows scrambling to figure out what to do, particularly those that film in NYC.

John Stewart and Steven Colbert's back-to-back Comedy Central shows took the night off, as did Jimmy Kimmel's show, which was scheduled to tape live in Brooklyn this week instead of Los Angeles. Kimmel was disappointed to have to cancel the live taping, tweeting to fans that their safety was most important. That tweet has since been removed. According to Twitter, Kimmel's show is planning to air Tuesday night, featuring Howard Stern and Tracy Morgan. 

Jimmy Fallon and David Letterman each continued with their scheduled shows, minus one seemingly critical element - an audience. Both shows taped to empty studios, except for Jimmy who had one person in his audience, "Late Night With Jimmy Fallon" writer Mike Dicenzo, also known as Mets Hat Guy. Check out Jimmy's cold open below. Get ready, the only laughter is that of the producers and band. Pretty crazy.

Subways and transit tunnels throughout NYC remain paralyzed today. CNN has been broadcasting around the clock since Hurricane Sandy began making her way up the east coast. Last night Erin Burnett reported live from Battery Park City in a rushing flood of water. Anderson Cooper reported from Asbury Park, NJ on the Jersey shore, one of the most damaged areas. The live feed cut out several times and Anderson and his news colleagues took shelter from thrashing rains behind the side of their news truck. News networks seemed to cut no corners making sure live Sandy coverage made it into American homes.

According to The Huffington Post, CNN brought in the most viewers in the "coveted" 25-49 age demographic among cable news networks last night. CNN won the demo by bringing in more than 1 million viewers, and a total of 3.4 million viewers. Fox News brought in a total of 3.5 million viewers, with 875,000 viewers in the demographic. MSNBC brought in a total of 1.4 million viewers, and 477,000 in the demo.

Overall, the major TV winner Monday night may have been the one with the most expertise on Sandy- the Weather Channel. According to The Hollywood Reporter, The Weather Channel brought in over 40 million viewers by streaming coverage live online. Considering the strength of this natural disaster, it's no wonder people were looking to the experts.
