Here, for the first time, online researcher Dynamic Logic revealed the secrets to getting viral videos passed around. The answer, apparently, is the same concept that works in Hollywood. â€oeThe video has to have legs,†said Michelle Eule, VP-research at Dynamic Logic, during a presentation Thursday afternoon at OMMA Video.

By legs, though, Eule didn’t necessarily mean the traditional show biz term, though if you have the kind of viral video legs Eule means, you’ll probably get the other kind too: the kind that keep your video popular and highly viewed.

Legs, as it turns out, stands for four key elements that the most successful viral videos have in common: Laugh, Edgy, Gripping, Sexual â€" or the acronym LEGS.

The results were based on a study Dynamic Logic did analyzing consumer reactions to some of the most popular and some not-so-popular viral video ads. What the Big 5 â€" including Ikea’s â€oePig Chase†â€" all had in common said, Eule, was that they made viewers laugh out loud, they contained edgy content, they were gripping, and they had sexual content.
