Cleveland Browns
The history of the Cleveland Browns American football team began in 1944 when taxi-cab magnate Arthur B. "Mickey" McBride secured a Cleveland franchise in the newly formed All-America Football Conference (AAFC). Paul Brown was the team's namesake and first coach. The Browns began play in 1946 in the AAFC. The Browns won each of the league's four championship games before the league dissolved in 1949. The team then moved to the more established National Football League (NFL), where it continued to dominate. Between 1950 and 1955, Cleveland reached the NFL championship game every year, winning three times.
History of the Cleveland Browns
Cleveland's first regular-season game took place September 6, 1946 at Cleveland Municipal Stadium against the Miami Seahawks before a then-record crowd of 60,135. That contest, which the Browns won 44–0, kicked off an era of dominance. With Brown at the helm, the team won all four of the AAFC's championships from 1946 until its dissolution in 1949, amassing a record of 52 wins, four losses and three ties. This included the 1948 season, in which the Browns became the first unbeaten and untied team in professional football history. The Browns had few worthy rivals among the AAFC's eight teams, but the New York Yankees and San Francisco 49ers were their closest competition.
