As of 4:20 p.m. ET, a year to the day the video was posted, the YouTube sensation has been viewed 1,742,458,065 times - and probably more since you first clicked on this story. That makes it the most watched YouTube video ever, surpassing Justin Beiber's "Baby" video in December.

A month after the video took off, the then-about-to-be-household-name told us what the song was about: "Gangnam means, it's like Beverly Hills of Korea," said Psy, or Jae-Sang Park. "But the guy doesn't look like Beverly Hills, dance doesn't look like Beverly Hills … and the situation in music video doesn't look like Beverly Hills. But he keeps saying I'm Beverly Hills style. So that's the point. It's sort of a twist."
