Since his retirement, Johnson has been an advocate for HIV/AIDS prevention and safe sex,[7] as well as an entrepreneur,[2] philanthropist,[9] broadcaster and motivational speaker.[10] His public announcement of his HIV-positive status in 1991 helped dispel the stereotype, still widely held at the time, that HIV was a "gay disease" that heterosexuals need not worry about; his bravery in making this announcement was widely commended.[11] Named by Ebony magazine as one of America's most influential black businessmen in 2009,[6] Johnson has numerous business interests, and was a part-owner of the Lakers for several years. Johnson also is part of a group of investors that purchased the Los Angeles Dodgers in 2012 and the Los Angeles Sparks in 2014.[7] During Johnson's ownership of both teams, the Sparks won the 2016 WNBA championship, and the Dodgers won the 2020 World Series championship. Combining his playing career and sports ownership career, Johnson has 10 NBA championships, five each as a player and later as a minority-owner of the Lakers.[14]
