"I built all the AI, the ranking, and we built the first, as far as I know, the first ranked content feed, and I built all the rank and the AI behind it," Bosworth told The Verge.
"It consumed me more fully than anything in life had ever consumed me," Bosworth told The Los Angeles Times in 2011.
Bosworth also told The Los Angeles Times that the News Feed was initially met with a backlash from users, who found it too intrusive.
"That passionate outpouring of sentiment, much of it negative, was being fueled by News Feed itself. That's when I realized how big the opportunity was at Facebook. I would have preferred a fan group to a protest group, but the fact that people felt that passionately about the product at all was very humbling and eye-opening," Bosworth said.
As Bosworth's career at Facebook progressed he went on to lead teams that built products, including Facebook Messenger and Groups.
