Before the
2004 college football season, the Atlantic Coast Conference determined its champion via round-robin play during the course of the regular season and there was no conference championship game. In 2004, the Atlantic Coast conference added two teams—
Virginia Tech and
Miami—expanding the league to 11 teams. At the time, college football teams were limited by the NCAA to 11 regular-season games, three or four of which typically featured teams outside the home team's conference. Following the 2004 season, the league added a 12th team—
Boston College—and became eligible to hold a championship game at the conclusion of
the 2005 season. The conference was divided into two divisions of six teams each. The team with the best conference record in each division is selected to participate in the championship game. In the inaugural championship game, which took place at the end of the 2005 college football season, the
Florida State Seminoles defeated Virginia Tech 27–22 at
Alltel Stadium in
Jacksonville, Florida. In the 2006 game, two other teams faced off as
Georgia Tech played
Wake Forest. Wake defeated Georgia Tech 9–6. For the 2007 game, Jacksonville was awarded a one-year extension as host, and the game remained in Jacksonville. Virginia Tech returned to the ACC Football Championship game and faced off against
Boston College. Tech won the game, 30–16, and returned to the championship in 2008 to defeat Boston College again 30–12. In 2009,
Georgia Tech defeated
Clemson, 39–34, but was forced to vacate the ACC championship by the NCAA. Following the 2007 game the Gator Bowl Committee—organizers of the ACC Football Championship game in Jacksonville—announced they would not seek another contract extension due to falling attendance. With Jacksonville's withdrawal from future
site selection, the ACC selected
Tampa, Florida and
Charlotte, North Carolina as future sites of the game. The 2008 and 2009 games were held in Tampa and the 2010, 2011, 2012, and 2013 games were held in Charlotte before it was announced as the extended home of this game through at least 2019. After a political dispute led to a one-game 2016 foray to Orlando, the ACC Championship Game has been played in Charlotte ever since. On June 28, 2022, the ACC announced that with the NCAA Division I Council ruling that conferences would no longer be required to maintain divisions in order to hold a conference championship, it would be eliminating its divisions for the 2023 season and onwards, opting instead for a 3-5-5 scheduling format instead. This means that the ACC Championship will no longer be determined by the two division winners, but will instead have the two teams with the highest conference winning percentage face each other. ==Conference expansion==
