News in brief: AI boost to video streaming; Mayer loses bonus; move to tackle comment trolls

Artificial intelligence is everywhere these days – it's even being deployed to improve your movie-watching experience. Todd Yellin, vice-president of innovation at Netflix, told an audience at Mobile World Congress in Barcelona this week that the streaming giant has been using AI to analyse each shot and adjust the compression accordingly to try and hit a sweet spot where the quality isn't noticeably affected while at the same time improving delivery of what you're watching. "We're allergic to rebuffering", Yellin said, explaining that the aim is to improve the experience for the growing number of people who watch Netflix content on mobile devices. The technology is called Dynamic Optimzer, and Yellin said it will be introduced "some time in the next couple of months". Yahoo chief executive Marissa Mayer won't be getting her bonus or her stock award after an independent investigation found that senior executives at the company mishandled the two huge breaches, NPR reported on Thursday.
