Apparently, the secret is to think like a toddler. If you’ve never heard “Baby Shark”, you’ve somehow managed to escape the most infectious song in recent memory. The “Baby Shark” video, consisting of a simple animation of a family of cute sharks, has over 2 billion views on YouTube. It nearly outranked Lady Gaga on the Billboard charts, and there are hundreds of thousands of videos unofficially featuring the song. And for the true fan, there’s a live show featuring every member of the Baby Shark family. “Baby Shark” wasn’t an accidental viral hit. Pinkfong, the Korean educational entertainment brand that created “Baby Shark”, has become a toddler music juggernaut over the past few years. Part of Pinkfong’s success is their attention to all aspects of what makes a song catch on: including creating dances tailored to the limited motor skills of pre-verbal children. “When we're working on our choreography, we have to create something for children so that they can easily copy us,” says Paik So-young, a content creator at Pinkfong. “We study which hand movement or leg movement will be fun for the children.” VICE News visited the Pinkfong headquarters in Seoul, South Korea, to see how baby hits are made.
