Guinness World Records (also know as Guinness Book of World Records) is a reference book published annually, listing world records both of human achievements and the extremes of the natural world. The book was co-founded by twin brothers Norris and Ross McWhirter in August 1955.
In January 1988, Tina set a Guinness World Record for the 'largest paying concert attendance for a solo artist' by performing in front of approximately 188,000 people at Maracana Stadium in Rio de Janeiro, Brazil. Tina replaced the previous record from Frank Sinatra, who played in front of 170,000 people eight years earlier at the same location.
In 2000, Guinness World Records announced that Tina sold more concert tickets than any solo performer in music history.
