Mark Zuckerberg has taken the stage to deliver a keynote at F8, Facebook's annual developer's conference.
The CEO addressed Facebook's ongoing data privacy scandal , election meddling issues, and fake news problems, recapping the company's efforts to fix those problems. But he also tried to move the narrative forward with new product and feature announcements.
"We are all here because we are optimistic about the future," said Zuckerberg. "We have real challenges to address but we have to keep that sense of optimism too. What I learned this year is we have to take a broader view of our responsibility."
Zuckerberg called out "Watch Party," a tool announced in January that lets you watch shows while chatting about them with your Facebook friends.
"Let's say that your friend is testifying in congress, for example. Now you're going to be able to bring your friends together and you can laugh together and you can cry together. Some of my friends actually did this! Let's not do that again anytime soon," Zuckerberg said.
And Facebook is adding new features for dating, Zuckerberg announced.
"This is going to be for building real long term relationships, not just hookups, it's going to be in the Facebook app but it's totally optional. It's opt in... we have designed this with privacy and safety in mind from the beginning... you will only be suggested people who are not your friends."
The event comes more than a month after news broke that Cambridge Analytica, a data firm with ties to President Donald Trump's campaign, accessed information from as many as 87 million Facebook users without their knowledge.
Shortly before Zuckerberg's keynote began, the company announced a new privacy feature that will, once launched, allow users to clear their browsing history on Facebook, including what they've clicked on and which websites they've visited.
