Thursday Night Football started in 2006 with an eight-game schedule exclusively on NFL Network. By 2012, Thursday Night Football had grown to a 13-game schedule exclusively on NFL Network, where it remained through the 2013 season.
In 1990, the NFL re-introduced a bye week to the schedule, which it had not had since 1966. Each team played sixteen regular season games over seventeen weeks. During the season, on a rotating basis, each team would have the weekend off. As a result, opening weekend was moved up to Labor Day weekend.
