The birth of a baby into a royal family has always generated global interest. It’s no different in our 24/7 era.

So when the Duke and Duchess of Cambridge announced the birth of their first-born today, it was fitting that the team at Clarence House (@ClarenceHouse) quickly turned to Twitter to send out the word to well-wishers everywhere.

The first confirmation that a royal arrival was imminent came at 7:37 a.m. BST this morning when the couple’s official Twitter account @ClarenceHouse tweeted:

The scale of the global conversation was immediately apparent. Since that announcement, there have been more than two million mentions of the news on Twitter, with well-wishers gathering around hashtags including #RoyalBaby, #RoyalBabyBoy and #RoyalBabyWatch.

The peak in conversation on Twitter about the news came at 8:37 p.m. BST in the minutes following the announcement of the baby’s birth, with more than 25,300 Tweets per minute.

As royal-watchers all over came together to share their excitement, the hashtag #RoyalBaby became the gathering place for messages of congratulations. Since the Duchess was admitted to hospital, that hashtag alone has been used more than 900,000 times on Twitter.

While @ClarenceHouse was the official source of information on Twitter, eager photographer Jesal Parshotam (@therealjesal) staked a claim to being the first to break the #RoyalBaby news, sending this Tweet at 5:55 a.m. BST this morning:

After a long day, anticipation turned to celebration as a series of Tweets were sent by @ClarenceHouse at 8:35 p.m. BST this evening announcing the safe delivery of a baby boy weighing 8 pounds, 6 ounces at 4:24 p.m. BST:

Notice of the birth was also displayed on an easel outside Buckingham Palace, and that image was shared around the world on Twitter:
