Which artist created the 24-hour music video for the 2013 song “Happy”?

Pharrell Williams created the 24-hour music video for his 2013 song “Happy.”

The project was presented as the world’s first 24-hour music video. Instead of one short narrative, it consists of a looping four-minute performance repeated across a full day, with different people dancing and lip-syncing around Los Angeles.

The online project was directed by French duo We Are From L.A., while Williams appears at intervals throughout the extended presentation. Viewers can select different points in the day, making the work function as an interactive web experience as well as a music video.

The standard short video for “Happy” was also widely circulated, so the title can refer either to the conventional clip or the much longer interactive version. The song appeared on the Despicable Me 2 soundtrack before being included on Williams’ album Girl.
