Heroes is an American Emmy Award-nominated science fiction drama tv show, created by Tim Kring, which premiered on NBC on September 25, 2006. The show tells the story of several people who "thought they were like everyone else... until they realized they have incredible abilities" such as telepathy, time travel, flight and instantaneous regeneration. These people soon realize they have a role in preventing a catastrophe and saving mankind. The series emulates the writing style of American comic books with short, multi-episode story arcs that build upon a larger, more encompassing arc. Kring said "we have talked about where the show goes up to five seasons."

When the series premiered in the United States, it was the night's most-watched program among adults aged 18-49, attracting 14.3 million viewers overall and receiving the highest rating for any NBC drama premiere in five years. On October 6, 2006, NBC Entertainment President Kevin Reilly announced Heroes had been picked up for a full season, and on January 17, 2007, Reilly announced Heroes had been picked up for a second season. The second season of Heroes will consist of 24 episodes, and the first season of a new spinoff, Heroes: Origins, will include six episodes. The second season is scheduled to premiere on September 24, 2007.
