FlashForward is an American television series, adapted for television by Brannon Braga and David S. Goyer, which aired for one season on ABC between September 24, 2009, and May 27, 2010. It is based on the 1999 novel Flashforward by Canadian science fiction writer Robert J. Sawyer. The series revolves around the lives of several people as a mysterious event causes nearly everyone on the planet to simultaneously lose consciousness for two minutes and seventeen seconds on October 6, 2009. During this blackout, people see what appear to be visions of their lives on April 29, 2010, a global "flashforward" six months into the future.
In May 2010, ABC announced that FlashForward had been cancelled. The season finale for Season 1 was shot before it was known the show would be cancelled and showed another flashforward event happening more than 20 years in the future. This more closely followed the original book, which featured a flashforward that peered 21½ years into the future.
