The Pro Football Hall of Fame is the hall of fame for professional football in the United States with an emphasis on the National Football League (NFL). The hall opened in Canton, Ohio, on September 7, 1963, with 17 charter enshrinees. The Pro Football Hall of Fame is unique among North American major league sports halls of fame in that officials are not inducted. The National Baseball Hall of Fame and Museum,Naismith Memorial Basketball Hall of Fame and Hockey Hall of Fame have each inducted game officials as members.Canton, Ohio was selected as the location for the Hall of Fame for three reasons: First, the NFL was founded in Canton in 1920 (at that time it was known as the American Professional Football Association); second, the now-defunct Canton Bulldogs were a successful NFL team based in Canton during the first few years of the league; and finally, the community of Canton successfully lobbied the NFL to have the Hall built in their city. Groundbreaking for the building was held on August 11, 1962.
