The National Football Conference – Northern Division or NFC North is one of the four divisions of the National Football Conference (NFC) in the National Football League (NFL). Nicknamed the "Black and Blue Division" for the rough and tough rivalry games between the teams, it currently has four members: the Chicago Bears, Detroit Lions, Green Bay Packers, and Minnesota Vikings, with the latter three based within most definitions of the Upper Midwest. The NFC North was previously known as the NFC Central from 1970 to 2001. The Tampa Bay Buccaneers were previously members, from 1977, one year after they joined the league as an expansion team, until 2002 when they moved to the NFC South. The division was created in 1967 as the Central Division of the NFL's Western Conference and existed for three seasons before the AFL–NFL merger. After the merger, it was renamed the NFC Central and retained that name until the NFL split into eight divisions in 2002. The four current division teams have been together in the same division or conference since the Vikings joined the league in 1961. The Bears, Lions (known as the Portsmouth Spartans until 1934) and Packers have been in the same division or conference since the NFL began a conference format in 1933. Largely because the four teams have played each other at least twice a year, with the exception of the strike-shortened 1982 season, for more than 60 years (more than 80 years in the case of the Bears, Lions and Packers), the entire division is considered one very large rivalry. The division has a total of five Super Bowl wins. The Packers have won four and the Bears one, with the most recent happening at the conclusion of the 2010 season. Of the ten NFL teams with the highest winning percentage throughout their respective franchise histories, three of them are in the NFC North (the Packers, the Bears, and the Vikings). Conversely, the Lions have one of the lowest winning percentages in the NFL, including the first winless 16-game season in NFL history, in 2008. The division has the second-longest active Super Bowl drought (only ahead of the AFC South) and a 1–8 record in conference championships since 2007, with the only win being the Packers over the Bears in 2010. They have only clinched two Super Bowl berths in the 21st century, while the other NFC divisions each
