2005 was the year that the Bryan brothers first began to assert their dominance in the Doubles game. That year, they made the finals of all 4 Grand Slam tournaments - only the second time a men's pairing has achieved this feat in Grand Slams.

The Bryan brothers erased their disappointment of winning only the Bronze at the Beijing Olympic Games by romping home to take Gold at the London Olympics of 2012. Following their win in London, they embarked on a winning spree, winning the next four Grand Slam titles beginning from the US Open that year.

At the end of Wimbledon 2013, following their triumph at the All England Club, they became the first doubles pairing in history - men or women for that matter - to hold all 4 Grand Slams and the Olympic Gold Medal at the same time. The feat has been dubbed the 'Bryan Golden Slam'.
