For years, critics have argued that social media platforms harm young users, but those claims are now being tested in court for the first time. A landmark trial in California will examine whether major tech companies intentionally designed their platforms to keep children hooked—and whether they should be held legally responsible for the mental health consequences. This lesson explores the legal arguments, the human impact, and what the outcome could mean for the future of the internet.

MICHEL MARTIN, HOST: Social media apps have long been accused of harming kids. Now a jury will hear those claims for the first time in a trial kicking off in a Los Angeles courtroom today.
STEVE INSKEEP, HOST: A key question is whether tech companies deliberately built their platforms to addict young users. How the jury decides could reshape the tech industry.
MARTIN: NPR’s Shannon Bond is following the case, and she’s with us now. Good morning.
SHANNON BOND, BYLINE: Good morning, Michel.
MARTIN: So tell us more about how we got here. What are the details of this trial?
BOND: Yeah. So this case in California state court is being brought by a teenage plaintiff known as K.G.M. She says she started using social media at age 10, and she says her excessive use led to mental health problems, including depression and body dysmorphia. Now, the defendants in this case are Instagram, Facebook, YouTube and TikTok, and so this trial is going to be a rare look inside how some of the most popular and powerful social media platforms operate. Jurors are going to be presented with thousands of pages of internal documents. That includes research the companies themselves have conducted on children. They’re going to hear from expert witnesses. They’re going to hear from K.G.M. herself. Here’s Matthew Bergman, K.G.M.’s attorney.
MATTHEW BERGMAN: The public is going to know for the first time what social media companies have done to prioritize their profits over the safety of our kids.
BOND: And tech executives are also expected to take the stand, including notably Mark Zuckerberg, the CEO of Instagram and Facebook owner Meta, and Adam Mosseri, the head of Instagram.
MARTIN: So that’s quite a list. But, Shannon, I’m thinking that we have heard these kinds of claims a lot. Are there other cases like this?
BOND: Yeah. This case is actually just the first in a wave of lawsuits against social media companies. They’ve been brought by more than a thousand individual plaintiffs, hundreds of school districts and dozens of state attorneys general. And I should note Snapchat recently settled with the plaintiff in this first trial, but it’s also named in these other lawsuits. Now, broadly, in these cases, the plaintiffs are accusing these companies of designing features like infinite scroll and auto-playing videos, frequent notifications that they say make these apps nearly impossible for kids to put down. And they say in some cases, this has led to depression, eating disorders, self-harm – even suicide. And the plaintiffs are seeking monetary damages, as well as changes to the way these social media apps are designed.
MARTIN: And what do the companies say?
BOND: Well, as you’d expect, they dispute these allegations. They say they’ve worked to make their platforms safer for kids. They argue there’s no clinical diagnosis of addiction to social media, and they say a direct link between using social media and mental health problems in kids has not been proven. Now, the companies also say that federal law, including the First Amendment, protects the decisions they make about content, including the design of their platforms. I spoke with Eric Goldman, who’s a law professor at Santa Clara University. And he says if juries end up siding with plaintiffs, these cases could really change how not just social media but the larger internet works.
ERIC GOLDMAN: If the plaintiffs win, the internet will almost certainly look different. And probably it will be a far less conversational one than we have today.
BOND: He’s wary of courts or regulators getting involved in these design decisions.
MARTIN: Shannon, before we let you go, you said there are more than a thousand plaintiffs bringing similar cases. How does that work?
BOND: Yeah. Because there are so many, these cases have been combined into two big buckets – one in state court here in California, one in federal court. And depending how juries decide a handful of initial cases, including this one starting in LA, the parties could enter settlement talks that involve all of the plaintiffs. You know, and eventually, this could wind up similar to landmark settlements reached with the opioid manufacturers and tobacco companies, which led those industries to pay out billions of dollars to victims. That’s certainly what the plaintiffs are hoping for.
MARTIN: That is NPR’s Shannon Bond. Shannon, thank you.
BOND: Thank you.
