It's safe to say that Psy's hit Gangnam Style has reached unbelievable heights after officially passing the 1 billion hits mark in the space of a few months. But this isn't the first time a dance video has been popular over the interweb.
In Step up 4: Miami Heat, the mob creates a dance that goes viral. Celebrities are tweeting about it and news reporters are going crazy for it. The video quickly reaches millions of views and keeps rising.
So how does a Youtube video become such a sensation? We thought we'd look back at some of Youtube's biggest and best dance videos to see what makes a dance video such a hit.
Evolution of dance
Moving seamlessly between eras, from the robot to the chicken dance Jud Laipply has been viewed more than 205 million times for a reason, the video triggers nostalgia in the happiest of ways.
Flawless dance act
When Simon Cowell gets out of his throne to give a standing ovation you know you've done something right. With similar dance moves and style to Step Up, this dance crew blows away the crowd and the judges.
Insane robot dance
Much like Susan Boyle's first audition on the Britain's Got Talent, you don't see this one coming. What looks like a high school talent show with some pretty capable dances, turns out to be a jaw drooping, 'how does he does that?' performance.
JK wedding entrance
Unlike the majority of these videos, the men and women involved aren't great dancers, they're just happy to be celebrating a wedding. What makes the video such a hit, is the genuine and infectious joy evident throughout.
Train station dance
Most popular flash mob videos are just highly choreographed commercials, but that doesn't make them any less entertaining. This clip used a remix of "Do-Re-Mi" from The Sound of Music to win the crowd.
Step up 4: Miami Heat is out now on DVD.
