With its origins dating back to the United Kingdom in the late 19th century, tennis has become one of the most popular sports in the world, with its four Grand Slam tournaments often one of the most viewed championships on the annual sporting calendar.
Out of the four majors, perhaps the most illustrious tennis tournament is Wimbledon in England, which was the first ever Grand Slam championship.
Professional male tennis players play in the ATP tour while female tennis players participate in the WTA tour.
Some of the greatest ever tennis players from both genders include Pete Sampras, Bjorn Borg, Rod Laver, Margaret Court, Martina Hingis, Martina Navratilova, and present superstars Roger Federer, Rafael Nadal and Novak Djokovic.
