Sports Records and History

Roger Federer has had two major long-term sponsorships: Nike (apparel/footwear, 1998-2018) and Rolex (watches, since 2006). While Adidas sponsors him now, Nike was his primary apparel sponsor for most of his career when this question was likely written. Longines is a current sponsor but not one of the two most iconic partnerships.

As of 2009 when this question was written, the all-time record for weeks at World No.1 was held by Pete Sampras (286 weeks). Federer had surpassed this by 2012 and ultimately reached 310 weeks. At the time of this question, Federer did not yet hold the record.

In tennis tie-break rules, players change ends after every 6 points, and the serve also rotates. The player who received in the last game of the tie-break serves first in the next set. Since you served the first game of set 1, your opponent serves first in set 2. This maintains proper rotation balance.

Tennis originated in 12th-century France as 'jeu de paume' (game of the palm), played by hitting a ball with hands. It later evolved in England where racquets were introduced. While England formalized modern tennis rules, the game itself began in France.
