Facebook still intends to rely on algorithms to select some material to feature on the main part of the News Feed, much like newspaper editors determine what goes on the front page.
More space on the News Feed's front page and other sections space will be devoted to pictures and video in recognition of how dominant those visual elements have become on Facebook as smartphones and tablet computers equipped with high-quality cameras have made it easier to share snapshots and clips.
About 50 percent of the posts on News Feed include a photo or video now, up from 25 percent in late 2011, Zuckerberg said.
