What a great free marketing gift. Toward the start of the third quarter of Super Bowl 2013, the lights went out in a good chunk of the New Orleans Superdome. Fans took to Twitter with joking (blame Beyonce!) and serious (remember Katrina?) comments on the situation, but NBC's Revolution used it to promote the show, which is set in a world without electricity.

"Just a taste of what’s to come on March 25. #LightsOut #Revolution," wrote the official Twitter account for Revolution. After that they shared this tweet and photo:

The Walking Dead showrunner Glen Mazzara also tweeted, "Is this the beginning of the apocalypse? Or a lame stunt promoting Revolution?" The Vampire Diaries' Julie Plec added, "NBC and JJ Abrams just 'Revolution' photobombed the Superbowl."

So congrats to Revolution on their own free advertising during the Super Bowl, when ads were selling for around $3.8 million. We know the real winners of the night!
