Vertical videos now play full screen on YouTube’s apps

YouTube’s endorsement of vertical videos is a big deal. Despite some pleas from the Internet, people will instinctively shoot video vertically instead of awkwardly flipping their phone horizontally. The vertical video revolution is being pioneered by Snapchat founder Evan Spiegel who is emphasizing the format claiming that people are nine times more inclined to engage with vertical videos than horizontal videos.

Still, not everyone is on board the S.S. Vertical Video ship. An unnamed agency creative told Digiday last month they “hated” the format because it’s unnatural. “There’s no art to it. It’s haphazard,” they complained.

The refreshed apps are the cornerstone of YouTube’s strategy of focusing on mobile. YouTube CEO Susan Wojcicki said at VidCon Thursday that “more than half” of views are originating on mobile devices and mobile revenue increased 100 percent year over year. YouTube said its early testing of 360-degree video ads, like this one Coca-Cola Mexico, have been outperforming regular ads by 36 percent, so expect more of those too.
