<p>**This episode contains discussion of bullying, abuse and suicide** A landmark trial is underway in Los Angeles where tech giants Instagram and YouTube will face a jury for the first time over claims that their platforms are deliberately designed to be addictive for children. Lawyers for the plaintiff – a 20 year-old woman – say she developed mental health issues after becoming addicted to the social media at an early age. They argue these companies built “addiction machines” with algorithms that learn what users want and keep feeding it to them. Instagram and YouTube deny the allegations, saying that they have no incentive to turn children into addicts and have introduced various safety measures. Meta CEO Mark Zuckerberg is expected to testify later this week. We speak to the BBC’s North America Technology Correspondent Lily Jamali, who has been following the case, to ask whether social media is having a generational reckoning – its Big Tobacco moment.
