Windfall is a serial drama television series about a group of people in an unnamed small city who win almost $400,000,000 in a lottery. The series premiered Thursday, June 8, 2006 on NBC, taking the time slot occupied by ER during the rest of the year.
On August 31, 2006, NBC announced the show's cancellation by stating on its website that the episode that night would be the series finale. Controversially, NBC also gave local affiliates the option of showing pre-season football instead and showing the final episode at each affiliates discretion. Many affiliates took them up on this, planning to show it either much later that night or at other odd days/times during the Labor Day weekend (for example, WNBC-TV in New York planned to show the episode at 12:30pm on September 3, 2006).
