Heroes is an American science fiction drama television series, 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 woke with incredible abilities" such as telepathy, time travel and flight. These people soon realize they have a role in preventing a catastrophe and saving mankind.

The series loosely follows the writing style of American comics by doing short, multi-episode story arcs that build upon a larger, more encompassing arc. Even with small story arcs that move the story forward, 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. On January 17, 2007, Reilly announced Heroes had been picked up for a second season.
