The "Gangham Style" video has been watched so many times since it appeared in June 2012 that the YouTube view counter stopped tracking views after 2,154,200,908.
On Dec. 1, YouTube posted, “We never thought a video would be watched in numbers greater than a 32-bit integer (=2,147,483,647 times).”
YouTube adds it “has been viewed so many times we had to upgrade to a 64-bit integer (9,223,372,036,854,775,808)!”
The video has been quite the phenomenon. In 2012, “Gangnam Style” held the Guinness World Record for most “liked” video in YouTube history. Korean pop star Psy starred in a Super Bowl ad in 2013. And world leaders, including President Obama and British Prime Minister David Cameron, have danced to the beat.
