FlashForward is an American television series, adapted for TV 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 appears to be visions of their lives on April 29, 2010, a global "flashforward". The original book explains a FF event that shows the world participants a view 21.5 years into the future, while the show shows a 6 month in the future FF event, probably coinciding with the shows first season enddate.
