By the time the newlyweds drove away as a married couple, Twitter users had tweeted up a storm of more than 3 million tweets -- double the volume generated by this year's Super Bowl and rivaling the Twitter activity around the 2010 World Cup Final, which was a standout worldwide social media event.
Wedding-related phrases, from "William & Kate" to "Grace Kelly" to "#rw2011," also dominated all of the top 10 trending worldwide terms.
The hashtag #proudtobebritish continued to swell until it became the top trending term worldwide. The hashtag, which steadily gained steam throughout the event, seemingly echoed a tweet posted by Victoria Beckham Thursday.
"London looks beautiful!!!we are so proud to be British! X VB x," she wrote.
But not all trends on Twitter were so prim and proper. Cheeky tweeters started posting "QILF" and "PILF" in messages commenting on "gorgeous" Middleton and her brother-in-law Prince Harry.
"Prince Harry in that uniform...I soooooo would ;) #PILF," said one tweeter.
Middleton's sister Pippa (Philippa) Middleton was also a trend on Twitter, even attracting a mention from sometime Twitter king Justin Bieber.
"congrats to William and Kate ...and Kate's sister. She was a hit with @thatrygood," he wrote, apparently referring to his friend Ryan Good.
William and Kate's balcony kisses also made it into the top 10 trends in the U.S., although the first one – a brief peck -- garnered mostly negative commentary. The second kiss, however, won over Twitter romantics who tweeted more celebratory posts.
Camilla Parker-Bowles, Prince Charles' wife, also took a few blows on Twitter, as critics bashed her fashion sense and lamented that Princess Diana couldn't attend the wedding instead.
Eight of the top 10 Google searches early Friday morning were related to the wedding, including searches for "Princess Diana" and "Bentley."
According to Yahoo, Middleton's dress, shoes and tiara spiked in search, as did the questions, "What do royal earls do?," "What does pippa mean?" and "What is William prince of?"
The wedding also broke a record for live streamed video, previously held by the 2010 World Cup. According to Akamai Technologies, Inc., a leading Web services company that monitors Internet traffic, concurrent live streams of the royal wedding served by the company surpassed the World Cup's 1.6 million. The company also said it saw a "clear spike" in traffic in its News Index, which monitors real-time global news consumption, and noticed elevated traffic in Europe.
Keynote Systems, a leading mobile and Internet performance monitoring company, said the wedding was also a major mobile event. At around 4:30 a.m. and 6:30 a.m. ET, the company said the response time for several major news outlets' mobile sites nearly doubled, indicating increased interest in accessing the news at those times.
In the week leading up to the royal wedding, chatter intensified online. Over the past week, Twitter users posted 2.1 million messages about the wedding (a number surpassed in just the first half of the royal wedding day itself) and Facebook users in the US posted 1.77 public status updates with the phrase "royal wedding."
