Founded in 2012 by two Stanford students, Snap is the Los Angeles-based technology and social media company behind messaging app Snapchat.
Snapchat, meanwhile, sees the âPlanet Earth IIâ show as content designed to live on its own, a way to refashion a popular TV franchise for its digital audience. The service is running ads in the show, with Goldman Sachs among the sponsors for the first episode. The six-episode Snapchat show will premiere on Feb. 17, the day before the television premiere of the âPlanet Earth IIâ nature documentary series in the U.S. (on BBC America) and Canada (on BBC Earth) on Feb. 18.
