1 big thing: Tech platforms struggle to police deepfakes

Mark Zuckerberg said Thursday that he's giving up setting annual challenges for himself and trying to take a longer view. But 2020 has already thrown down a challenge for him: threading a needle between business demands and political landmines, as Sara reports. The big picture: Zuckerberg has to grow revenue and users, yet not get blamed for tipping another election -- and not buckle on what he views as the core value of free speech. Despite continuing criticism for Facebook and Zuckerberg in particular, he seems to be dodging any genuinely damaging blows -- for now. The reality: Facebook's revenue and user base have shown consistent growth over the past year, suggesting that users and advertisers aren't too spooked by the controversies around data privacy and misinformation.
