More than 29 million people watched on television in the United States as Britain's Prince Harry married American actress Megan Markle, according to Nielsen ratings released Sunday.
It exceed the number for the 2011 wedding of Harry's brother Prince William to Kate Middleton, which was watched by 22.8 million people.
Over six million people tweeted on Prince Harry's marriage to Meghan Markle, more than three times the number during his older brother's wedding, social media monitoring firm Visibrain said Sunday.
Between 2200 GMT Friday and 2300 GMT Saturday, 6,604,498 tweets were posted worldwide on the royal nuptials, of which 5.2 million bore the hashtag #RoyalWedding, the French firm said.
That compared with 1,821,669 tweets across a similar timeframe for Prince William when he married Kate Middleton back on April 29, 2011 when Twitter, founded in 2006, was in its relative infancy.
The most picked up post was by Lucy Sempey and was retweeted nearly 105,000 times. It was a photograph of Markle outside Buckingham Palace as a teen with the message: "One day you’re 15 and posing outside Buckingham palace and 22 years later you’re marrying the Prince. Unreal."
Harry and Meghan tied the knot in a ceremony at Windsor Castle, where they were greeted by around 100,000 people lining the streets.
The couple will not be taking a honeymoon immediately, as they are due to attend a charity garden party for Prince Charles, the heir to the throne, at Buckingham Palace on Tuesday.
