YouTube said the video � its most watched ever � has been viewed more than 2,147,483,647 times. It has now changed the maximum view limit to 9,223,372,036,854,775,808, or more than nine quintillion. Gangnam Style became a worldwide hit when it was released in 2012, largely due to the surreal video. How do you say 9,223,372,036,854,775,808? Nine quintillion, two hundred and twenty-three quadrillion, three hundred and seventy-two trillion, thirty-six billion, eight hundred and fifty-four million, seven hundred and seventy-five thousand, eight hundred and eight. YouTube�s counter previously used a 32-bit integer, which is a unit used to represent data in computer architecture. This means the maximum possible views it could count was 2,147,483,647.On 1 December, it posted a statement saying: �We never thought a video would be watched in numbers greater than a 32-bit integer� but that was before we met Psy.� Google, which owns YouTube, later told website The Verge that engineers �saw this coming a couple months ago and updated our systems to prepare for it�. YouTube now uses a 64-bit integer for its video counter, which means videos have a maximum viewer count of 9.22 quintillion. Psy has yet to comment although news of YouTube�s change was posted on his Facebook and Twitter pages. The second most-watched video on YouTube � Baby by Justin Bieber � lags behind Gangnam Style by more than a billion views.
