Canada at the Summer Olympics became the first Canadian Summer Olympian to win a medal in four straight Olympics. After George Hodgson won two gold medals in the 1912 Stockholm games, it would be 72 years before Alex Baumann became the second Canadian swimmer to win Olympic gold, when he won both individual medley events in world record time in the 1984 Los Angeles games. Victor Davis (1984), Anne Ottenbrite (1984), Mark Tewksbury (1992) and Penny Oleksiak (2016) are the only other Canadian swimmers to win gold medals. In 2004, Canada failed to win a medal of any colour in swimming for the first time
Montenegro at the 2008 Summer Olympics water polo team won the 2007 European Water Polo Olympic Qualification Tournament to qualify for the Olympic games. Montenegro failed to win any medals, but did advance to the bronze medal match in men's water polo, where they lost to Serbia, 6-4. Montenegro created its National Olympic Committee in 2006, and gained International Olympic Committee recognition in 2007 during the IOC's meetings in Guatemala City. Previously, Montenegrin athletes competed as part of the Serbia and Montenegro team in 2004, and as part of Yugoslavia teams before that. Montenegro was also part of the Yugoslavian team in 1992 Summer Olympics that
