The Los Angeles Lakers are a professional basketball team based in Los Angeles, California that competes in the National Basketball Association (NBA), which was formerly called the Basketball Association of America (BAA). Since 1999, the Lakers have played their home games at Staples Center. The Lakers' franchise was founded in 1947 in Minneapolis, Minnesota. The first owners purchased the disbanded Gems from Detroit, Michigan, then renamed and moved the team. It was in Minneapolis where the Lakers received their official title from Minnesota's nickname, Land of 10,000 Lakes. The Lakers won five championships before relocating to Los Angeles for the 1960–61 NBA season. The Lakers went on to lose all of their eight appearances in the NBA Finals in the 1960s, despite the presence of Elgin Baylor and Jerry West. In 1972, the Lakers compiled a 33-game winning streak, the longest streak in U.S. professional team sports, and won their sixth title, under coach Bill Sharman. The Lakers' popularity soared in the 1980s when they won five additional championships during a nine-year span with the help of Hall of Famers Magic Johnson, Kareem Abdul-Jabbar, James Worthy and coach Pat Riley, the franchise's all-time leader in both regular season and playoff games coached and wins. Two of those championships during that span were against their arch-rivals, the Boston Celtics. With the help of Shaquille O'Neal, Kobe Bryant, and Hall of Fame coach Phil Jackson, the Lakers played in seven NBA Finals between 2000 and 2010, winning three of them consecutively from 2000 to 2002, losing the next two in 2004 and 2008, and winning in 2009 and 2010; the last three appearances were without O'Neal.
