A royal wedding for the 21st century. It was broadcast on YouTube, live updates were pushed from Clarence House - the princes' official residence - via Twitter and Facebook. An official hashtag even helped to pull the audience together.
Official notes and updates from the royal family and media outlets were not only the backdrop, though. The running commentary from everyday people provided the same buzz and excitement online as that which emanated through the London air.
Will and Kate made it clear early in their marriage preparations that they wanted a wedding for the people, that everyone could enjoy.
With that in mind, the monarchy turned to the web and embraced social media whole-heartedly.
A Facebook page was updated hourly. The @ClarenceHouse Twitter page kept track of key developments and quickly gathered tens of thousands of followers. A YouTube channel accepted congratulations from people around the world, giving them a direct line to the royal couple.
Flickr - the popular photo sharing site - was used to release exclusive photos of Buckingham Palace, the carriage, Westminster Abbey and dozens of other behind-the-scenes images.
Then, on the day of, the entire live event was streamed live on YouTube for anyone with an Internet connection to see.
More than 2 billion people are estimated to have taken in the event, many using the common hashtag #rw2011 to join the conversation and the celebrations on Twitter.
"Diana would be so proud of her boys today," one woman wrote to little more than 100 followers on Twitter. "She's definitely there with Prince William today."
As the now Duchess of Cambridge emerged from her hotel, the online world exploded with glimpses and guesses about her dress, her hair, her tiara and her shoes.
"Cathedral veil ... sleeves ... oh my!!!" wrote one person, followed by: "The hair is down. I repeat the hair is down!"
"Sleeves! V-neck! Lace! That's all I've got so far..." wrote QMI's own national life editor Rebecca Zamon.
"OMG these glimpses of Kate are killing me!" wrote another watcher.
It was a tone that marked most of the day. From the arrival of the first guests to the last of three kisses atop the balcony of Buckingham Palace, it was a wedding for the people and largely told by the people.
And as appropriately as it ended in person - hand-in-hand, walking back into the palace, with a radiant smile over her shoulder to the crowds - so to were the breathless online observers happy to see them disappear and enjoy the rest of their special day with friends and family.
"Good God ... she is so beautiful," wrote Karen Leggett, followed by Theresa Mendler in Ontario: "Kiss!!! Happily. Ever. After."
