a 15% minority ownership share in the English football club Leeds United F.C.; in 2021, this stake was increased to 44%. Franchise history Morabito family era (1946–1976) Buck Shaw years (1946–1954) The San Francisco 49ers, an original member of the new All-America Football Conference (AAFC), were the first major league professional sports franchise based in San Francisco, and one of the first major league professional sports teams based on the Pacific Coast. In 1946, the team joined the Los Angeles Dons of the AAFC and the Los Angeles Rams of the rival National Football League as the first three teams playing a "big four"-sport in the Western United States, eventually becoming part of the NFL themselves in 1950. In 1957, the 49ers enjoyed their first sustained success as members of the NFL. After losing the opening game of the season, the 49ers won their next three against the Rams, Bears, and Packers before returning home to Kezar Stadium for a game against the Chicago Bears on October 27, 1957. The 49ers fell behind the Bears 17–7. Tragically, 49ers owner Tony Morabito (1910–1957) collapsed of a heart attack and died during the game. The 49ers players learned of his death at halftime when coach Frankie Albert was handed a note with two words: "Tony's gone". With tears running down their faces, and motivated to win for their departed owner, the 49ers scored 14 unanswered points to win the game, 21–17. Dicky Moegle's late-game interception in the endzone sealed the victory. After Tony's death, 49er ownership went to Victor Morabito (1919–1964) and Tony's widow, Josephine V. Morabito (1910–1995). The 49ers' special assistant to the Morabitos, Louis G. Spadia (1921–2013) was named general manager. During the decade of the 1950s, the 49ers were known for their so-called "Million Dollar Backfield", consisting of four future Hall of Fame members: quarterback Y. A. Tittle and running backs John Henry Johnson, Hugh McElhenny, and Joe Perry. They became the only full-house backfield inducted into the Pro Football Hall of Fame. For most of the next 13 years, the 49ers hovered around .490, except for 1963 and 1964 when they went 2–12 and 4–10 respectively. Key players for these 49ers included running back Ken Willard, quarterback John Brodie, and offensive lineman Bruce Bosley. During this time the 49ers became the first NFL team to use the shotgun formation. It was named by the man who actually devised
