Searches for Kate Middleton on PornHub surged 920% on the day Princess Charlotte was born Getty

PornHub users have been revealed as apparent royalists after the X-rated website said searches for "Kate Middleton" rocketed an incredible 920% on the day Princes Charlotte was born. The surge in popularity came on 2 May, the day the Duchess of Cambridge gave birth at St Mary's Hospital in Paddington, London.

The Duchesses name was then out of favour for a day before searches boomed by almost 800% on 4 May. The wife of Prince William was at the middle of a media storm in September 2012 when French magazine 'Closer' has published topless photos of her on holiday with the heir to the throne. The couple won an injunction against the magazine prohibiting the photos' publication but not before they had been accessed on the Internet.

The spike was revealed after PornHub published details of viewers' habits from 2015. As well as the birth of the royal baby, other events that inspired a spike in visitors included the release of "Star Wars: The Force Awakens".

Searches for Star Wars-themed pornography were up by 1854% around the December 18 release date of The Force Awakens and fans of the fantasy genre were clearly driven to the frenzy during season five of the season as searches for "Game of Thrones" increased by 199% and 212% for the first and final episodes respectively.

The sporting event that had the biggest impact on PornHub's US visitors was last year's super-fight between boxers Floyd Mayweather and Manny Pacquiao. Traffic to the site was down by 27% during the fight, while a quarter of visitors stayed away from the website during the Super Bowl final between the New England Patriots and Seattle Seahawks.

Politics played a part in shaping porn viewers' habits. PornHub saw 12% fewer visitors in Venezuela on its election day last year while in Israel there were 3% fewer hits on its legislative election day. Ireland's "Late Late Toy Show" interrupted users' porn habits in November when 16% fewer visitors went to PornHub.
