The firefighter drama shows an intense rescue scene in the clip, while the J.J. Abrams sci-fi series gives a look at the world before and after the blackout in the preview video.
On the same day NBC unveiled its 2012-2013 primetime line-up, the first sneak peeks to its new shows made their way out online. Among them is a clip from "Chicago Fire" which follows a team of firefighters as they try to keep their team intact in a room set ablaze by fire.
"The New Normal", a new comedy from "Glee" creator Ryan Murphy, is previewed in a clip which shows a gay couple, played by Andrew Rannells and Justin Bartha, interviewing a woman (Georgia King), who is a potential surrogate.
A preview from J.J. Abrams' "Revolution" opens with a man who looks panicked as he tells his friend over the phone that everything is going to be turned off. After the blackout, a girl named Charlie, who just lost her father, tries to find her uncle and save her kidnapped brother.
"Go On" has a clip which shows Matthew Perry's Ryan, who recently lost his wife in a car accident, questions the qualifications of his new therapist. In a sneak peek of "1600 Penn", a hilarity ensues as the President of United States (Bill Pullman) is almost hurt in a silly accident.
More information and clips from other NBC's new shows can be obtained on the network's official site.
