A royal baby, a raunchy dance, a new Pope, a boy band and the crowning of Andy Murray as Wimbledon Champion were just some of the hot topics of conversation on Twitter in 2013.
The birth of the Prince of Cambridge in July sparked a frenzy of excitement on social networking sites which spread rapidly across the world.
A spike in conversation came in the minutes following the initial announcement, with more than 25,300 tweets per minute.
At the time, Twitter said the highest volumes of conversation came from the UK, the United States, Canada, France and Italy.
The day after his birth, more than 18,000 people a minute tweeted about the royal prince as he made his first public appearance with his parents on the steps of the Lindo Wing at St Mary's Hospital, Paddington.
But although it got people talking, the announcement of the royal baby's birth failed to generate the same flurry of activity on social media as Andy Murray's historic Wimbledon victory earlier in the month which amassed 120,000 tweets per minute, or the election of Pope Francis in March which sparked a massive 132,000 tweets per minute.
Elsewhere in the sporting world, football dominated the biggest spikes in UK Twitter traffic, with seven of the top 10 topics in terms of tweets per second being about the beautiful game.
The moment that Manchester United were knocked out of the Champions League after being beaten by Real Madrid took the number one spot.
Also achieving some of the most tweets per second was Mumford and Sons' closing set at Glastonbury in June, with millions marking the moment the band were joined on stage by The Vaccines and Vampire Weekend to sing Beatles classic With A Little Help From My Friends.
While the election of a new pontiff may be a centuries-old process it captured the imagination of the modern age - prompting seven million mentions on Twitter.
Cardinal of Buenos Aires Jorge Mario Bergoglio's election dominated online discussion to such a degree that it became the subject of eight of the top 10 trending topics at one point, according to Twitter.
