Serena Williams right and her sister Venus Williams stretch ahead of their singles match, at the All England Lawn Tennis Championships in Wimbledon, Monday.
But the world wants to know what’s happening, and the task of capturing and recording every single drop shot, volley and epic five-set comeback falls to IBM, the official technology partner at the All England Lawn Tennis Club.
Maria Sharapova will face CoCo Vandeweghe in the quarterfinals on Centre Court, while Novak Djokovic will resume his fourth-round match against Kevin Anderson on Court 1. He only got as far as the fourth round once before, also in 2009.
Study the images of some of those old days – the aftermath of the 2008 Wimbledon final, for example, which was the last time Venus emerged successful from a Grand Slam meeting with her sister – and you will see the changes time has wrought.
