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.
On Tuesday, CEO and founder Mark Zuckerberg said the company is adding a new privacy feature that lets you clear your browsing history on Facebook, including what you've clicked on and which websites you've gone to.
Zuckerberg also announced Facebook is launching a "Clear History", feature that will allow users to clear their search history and eliminate past information from websites and apps.
He said the service will be opt-in and, to preserve people's privacy, not viewable to users' friends.
Despite that inconvenience, Zuckerberg posited that the upcoming introduction of the new privacy control is in line with the demands of privacy advocates and consumers alike. Instead, he said, Facebook will suggest possible dating prospects.
Schroepfer told the DCMS committee that Facebook will introduce "radical transparency" in order to reassure the public over political advertising on the social network, with political adverts required to be labelled and authorised, with funding information published so users can see which group has paid for them.
"Let's not do that again soon", he quipped as the screen showed an image of his hours-long testimony on Capitol Hill last month. The committee gave Facebook until May 11 to provide those answers and respond as to whether Zuckerberg plans to testify. Take the "unlocking" feature, for example, basically the only aspect of Facebook Dating that wasn't scalped from Tinder, Bumble, or Hinge.
Damian Collins, a Conservative who heads the House committee, said United Kingdom lawmakers are prepared to send a summons compelling Mr. Zuckerberg's appearance in London unless he volunteers to provide oral testimony to investigators, according to a copy of the letter released by Parliament. This might include data like information related to Like button, Facebook Analytics, etc.
Facebook joins internet giants Amazon, Microsoft and Google in offering artificial-intelligence based translation features - most prominently Google's Pixel ear buds which promise real-time translation across dozens of languages.
Zuckerberg also announced new virtual reality hardware in the form of Facebook's Oculus Go headset. The issue was resolved but it was unclear exactly which Facebook updates caused the issues for Tinder. You may have to sign back in to every website, and you may have to reconfigure things. "We need to make sure they are used for good".
