A Brief History of the A's baseball club.

1901-1950 Team founded as Philadelphia Athletics, part of new American Baseball League. Cornelius "Connie Mack" McGillicuddy owned and ran the team for 50 years. During that time they won the World Series in 1910, 1911, 1913, 1929 and 1930. The club adopted the elephant mascot a year after its founding when rival New York Giants owner John McGraw called the team a "white elephant."

1955-1967 With the team struggling financially, Mack approves sale to Chicago businessman Arnold Johnson, who moves the A's to Kansas City, Mo., for the 1955 season. After his sudden death five years later, fellow Chicago-area businessman Charles O. Finley buys a controlling interest in the team from Johnson's estate and makes failed bids to move it to Texas, Kentucky and California. He also changes the team's colors from blue, red and white to green, yellow and white. With performance and attendance flagging, Finley secures approval to move the A's to the Oakland-Alameda County Coliseum, which opened two years earlier as home of the Raiders football team, for the 1968 season. They became the Bay Area's second Major League baseball team, joining the Giants who had moved west from New York 10 years earlier.

1968-1980 The A's prospered on the field in their new home, winning three consecutive World Series from 1972 to 1974 with stars including Reggie Jackson and Rollie Fingers. But attendance remained anemic. Finley explored possible A's moves to Chicago, New Orleans and Denver but was blocked by his Coliseum lease. In 1980 he sold the team to Levi Strauss & Co. president Walter Haas.

1981-1995 A's attendance rose with the departure of the Raiders for Los Angeles, and field performance improved with such star players as Jose Canseco, Mark McGwire and Dennis Eckersley. The A's swept their cross-bay rival Giants in the 1989 World Series, interrupted by the Loma Prieta Earthquake. After Haas' death, local real estate developers Steve Schott and Ken Hofmann buy the A's in 1995.

1996-2004 The Raiders' return to the Oakland Coliseum sours the A's relationship with local political leaders. The new owners begin floating relocation, possibly to San Jose. The team's strong performance under General Manager Billy Beane -- making the playoffs from 2000 through 2003 -- using statistical analyses inspired author Michael Lewis' 2003 book Moneyball, and a film version starring Brad Pitt in 2011. Relocation talk continues.

2005-present Los Angeles-based real estate developer Lew Wolff, who had worked with the A's on plans for a new stadium, buys the team with Gap clothing heir John J. Fisher. Wolff has a long history with San Jose, where he owns the Fairmont hotel and recently purchased the Sainte Claire Hotel. Wolff soon unveils a proposal for a new privately financed ballpark in Oakland but it goes nowhere. Also in 2005, San Jose's then-mayor Ron Gonzales urges pursuit of a downtown ballpark to lure the A's. Wolff in November 2006 announces Fremont ballpark plan but cancels it in February 2009. San Jose leaders immediately revive ballpark effort. In March 2009, baseball Commissioner Bud Selig calls for a committee to explore the A's ballpark options.
