Hollywood Reporter: Facebook CEO Mark Zuckerberg placed a big emphasis on video during the opening keynote address at the tech giant’s annual F8 developer conference in San Francisco. In Facebook’s early days, users shared primarily text content, Zuckerberg told the audience. Today, they share mostly photos. “Fast forward five years, it’s going to be video. If you look out even further, it will be more immersive content like AR and VR.”
