But over a year later - and four years after Facebook's $3 billion purchase of virtual reality company Oculus in 2014 - we've arrived at the next F8 developer conference, and it feels like no one is using Facebook Spaces.
Facebook now collects users' web browsing histories - even when they're not on Facebook - to use for targeted ads, and stores it for between 90 days and two years, according to Recode. The filters, popularized by Facebook competitor Snap, allow users to overlay augmented reality objects like mustaches or hats onto their face when they upload videos and images. "I took Wyclef Jean to Jupiter and went home with Hodor".
It will take months to build the new Clear History feature, Egan wrote, adding that the company will work with privacy advocates, academics, policy makers and regulators for input on how to remove personal information. Last year, Zuckerberg described his strategy for using VR to reshape the way people interact and experience life, much as the company's social network already has.
The move will create new competition for popular dating apps like Tinder, Hinge and Bumble. Users can chat one-on-one with another user or with a small group and they can keep the conversation going for as long as they want. The owner of a slew of dating apps including Match, Tinder and OkCupid, among others, Match Group is a leader when it comes to dating communities.
Match fell 22 percent - its largest one-day drop ever - and IAC, which owns more than a fifth of Match, fell almost 18 percent in its biggest daily loss in about 13 years. But some of these dating apps have started to pull away from Facebook.
Reiterating comments he made during recent media briefings, congressional hearings, and Facebook's latest quarterly earnings announcements, Zuckerberg reminded the audience of all the steps the company is doing to remedy its recent problems. He was grilled about how Facebook protects users' data and other issues.
The demonstration didn't seem to indicate a way for users to pick and choose who they release their event or group information to, instead painting it as an all or nothing game.
The Facebook CEO, in a post on his Facebook account, said he will discuss the feature at Facebook's annual F8 conference which begins today.
