Since YouTube launched in 2005, the video streaming site has seen 14 videos break the 2 billion views mark, Psy's "Gangnam Style" being the first to do so and even requiring YouTube to change its view capacity after hitting 2,147,483,647 in December 2014. But after Psy held the most-viewed video title for years, Wiz Khalifa's "See You Again" video (featuring Charlie Puth) officially overtook the top spot on the list on July 10.
Quickly gaining speed on the top two most-viewed YouTube vids is Luis Fonsi and Daddy Yankee's "Despacito," which has garnered more than 2.5 billion views in just six months and is well on its way to becoming the next No. 1 -- potentially simultaneous with its No. 1 title on the Billboard Hot 100, too.
