The first record in the 100 metres for men (athletics) was recognised by the International Amateur Athletics Federation, now known as World Athletics, in 1912.
As of 21 June 2011, the IAAF had ratified 67 records in the event, not including rescinded records.
The 1996 Summer Olympics (officially the Games of the XXVI Olympiad, also known as Atlanta 1996 and commonly referred to as the Centennial Olympic Games) were an international multi-sport event held from July 19 to August 4, 1996, in Atlanta, Georgia, United States. These were the fourth Summer Olympics to be hosted by the United States, making it the first country to have three different cities host the Summer Olympics. It also marked the 100th anniversary of the 1896 Summer Olympics in Athens, the inaugural edition of the modern Olympic Games. These were also the first Summer Olympics to be held in a different year than the Winter Olympics since the same time practice commenced in 1924, as part of a new IOC practice implemented in 1994 to hold the Summer and Winter Games in alternating, even-numbered years. The 1996 Games were the first of the two consecutive Summer Olympics to be held in a predominantly English-speaking country, preceding the 2000 Summer Olympics in Sydney, Australia. These were also the last Summer Olympics to be held in North America until 2028, when Los Angeles will host the games for the third time.
10,318 athletes from 197 National Olympic Committees competed in 26 sports, including the Olympic debuts of beach volleyball, mountain biking and softball, as well as the new disciplines of lightweight rowing, women's swimming 4 x 200 freestyle relay, women's fencing, team rhythmic gymnastics, and women's association football. A total of 24 countries made their Summer Olympic debuts in Atlanta, including 11 former Soviet republics participating for the first time as independent nations. With a total of 101 medals, the United States topped both the gold and overall medal count for the first time since 1984 (and for the first time since 1968 in a non-boycotted Summer Olympics), also winning the most gold (44) and silver (32) medals out of all the participating nations. Notable performances during the competition included those of Andre Agassi, whose gold medal in these Games would be followed up with the French Open title in 1999, making him the first men's singles tennis player to complete the Career Golden Slam; Donovan Bailey, who set a new world record of 9.84 for the men's 100 meters; Lilia Podkopayeva, who became the second gymnast to win an individual event gold medal after winning the all-around title in the same Olympics; and the Magnificent Seven, who dramatically won the first ever U.S. gold medal in the women's artistic gymnastics team all-around.
