===Umpires===
At The Championships at Wimbledon, forty-two chair umpires are assigned each day and usually work two matches a day. They use tablet computers to score each match and these scores are displayed on the scoreboards and on wimbledon.com.<ref>{{cite web |title=Umpires |url=https://www.wimbledon.com/en_GB/atoz/umpires.html |website=www.wimbledon.com |access-date=2 March 2023 |archive-date=2 March 2023 |archive-url=https://web.archive.org/web/20230302005701/https://www.wimbledon.com/en_GB/atoz/umpires.html |url-status=live }}</ref> Line umpires worked in teams of nine or seven. Teams of nine umpires worked the Centre Court and Court numbers 1, 2, 3, 12, and 18 with the remaining teams of seven working the other courts. These teams rotated, working sixty minutes on the court and then sixty minutes off.

In 2007 a new technology called Hawk-Eye was introduced.<ref>{{Cite news |date=23 May 2007 |title=Hawk-Eye to make Wimbledon debut |language=en-GB |work=BBC Sport |url=http://news.bbc.co.uk/sport2/hi/tennis/6684409.stm |access-date=21 July 2023 |archive-date=21 July 2023 |archive-url=https://web.archive.org/web/20230721114526/http://news.bbc.co.uk/sport2/hi/tennis/6684409.stm |url-status=live }}</ref> This technology showed whether the ball bounced in bounds or out. Wimbledon started using this technology but continued to use line umpires as well. However the players were only allowed to ask to see this 3 times during one set.<ref>{{cite web |last1=Addicott |first1=Adam |title=EXCLUSIVE: Wimbledon Says No To Replacing Line Umpires With Hawk-Eye, But Others Say Yes |url=https://www.ubitennis.net/2021/07/exclusive-wimbledon-says-no-to-replacing-line-umpires-with-hawk-eye-but-others-say-yes/ |website=UBITENNIS |access-date=1 March 2023 |date=9 July 2021 |archive-date=2 March 2023 |archive-url=https://web.archive.org/web/20230302005709/https://www.ubitennis.net/2021/07/exclusive-wimbledon-says-no-to-replacing-line-umpires-with-hawk-eye-but-others-say-yes/ |url-status=live }}</ref>

Line umpires and the ability to challenge calls made during a match were axed, starting from the 2025 Championships, due to the professional tennis tours adopting the Hawk-Eye Live technology from the 2025 season for any tournament capable of supporting it, bringing an end to the 147 years of traditional scenes of line umpires walking to and from the courts during matches. The only umpire on the court will now be the chair umpire, although the new role of match assistants will be created to escort players to the bathroom or take their racquets to the stringer.<ref name=line/><ref name= tech/>
