Historically, the Browns have been among the most successful franchises in American football history, winning eight titles during a short period of time—1946, 1947, 1948, 1949, 1950, 1954, 1955, and 1964. The Browns have never played in a Super Bowl, getting close five times by making it to the NFL/AFC Championship Game in 1968, 1969, 1986, , and . Former owner Art Modell's relocation of the Browns after the 1995 season (to Baltimore creating the Ravens), caused tremendous heartbreak and resentment among local fans. Cleveland mayor, Michael R. White, worked with the NFL and Commissioner Paul Tagliabue to bring back the Browns beginning in the 1999 season, retaining all team history. In Cleveland's earlier football history, the Cleveland Bulldogs won the NFL Championship in 1924, and the Cleveland Rams won the NFL Championship in 1945 before relocating to Los Angeles.
