Psy took the world by storm with his "Gangnam Style" music video in 2012, and it remains so popular that it broke the YouTube original view counter. Based on a 32-bit integer, the YouTube original view counter effectively maxed out at 2,147,483,647, and Google has now transitioned to a 64-bit view counter.
The new view counter can track a figure as high as 9 quintillion views, Google noted. "We never thought a video would be watched in numbers greater than a 32-bit integer (=2,147,483,647 views), but that was before we met Psy," a Google blog post reported. "'Gangnam Style' has been viewed so many times we have to upgrade!"
Gangnam Style still has a healthy lead in the top 10 most watched YouTube videos, and surpassed 2,152,512,000 video views as of late Wednesday morning.
