A landmark lawsuit has begun in California over the impact of Instagram and YouTube on mental health. The plaintiffs accuse the world’s largest social media companies of creating an “addiction mechanism”.
A hearing has begun in Los Angeles Superior Court in a case that could set a precedent.
“These companies created mechanisms designed to create addiction in the brains of children, and they did so intentionally,” said Mark Lanier, representing a plaintiff identified as KGM, who claims she suffered mental health issues as a result of her addiction to social media. Networks.
Lawyers for Meta and YouTube told jurors that K. G. M. arose from other problems in her life, not their negligence.
The plaintiff is referred to by her initials because the alleged injury occurred when she was a minor.
Lanier also accused Meta and YouTube of failing to warn young users about the dangers of their platforms’ design.
During his opening statement to the jury, the Plaintiff’s Representative used children’s cubes with the letters A, B and C, which in English begin with the words “addiction,” “brain” and “children.”
“This case concerns two of the wealthiest corporations in history that have developed an addictive mechanism in children’s brains,” Lanier said. In which Zuckerberg demanded that subordinates achieve “a 12% increase in time spent on meta-platforms” to meet internal business goals.
As for YouTube, Lanier said. It turns out the Google-owned platform intentionally targeted younger users because it could “charge advertisers more” than YouTube Kids.
Lanier accused YouTube of trying to capitalise on the needs of working parents looking for “digital childcare”.
Is Insta to blame or family issues?
Rep Meta’s attorney Paul Schmidt urged the jury to consider whether Instagram itself was a significant factor in K.G.M.’s mental health issues.
He described K.G.M. as someone who faced family turmoil, including neglect, physical and verbal abuse, and bullying from parents.
Schmidt told jurors he admired KGM because she “worked hard to overcome” her difficulties. He referred to records describing domestic violence in KGM’s family history. And referrals to therapists starting at age three.
Schmidt showed some of K.H.M.’s statements about her family life, including how her mother yelled at her, called her stupid and drove her to suicide.
“I understand it’s hard to hear,” Schmidt told jurors. The day of the trial, which is likely to last about a month and a half and will have major implications for similar lawsuits likely to be tried this year.
The court in Los Angeles will test legal arguments put forward by families who say they have seen their children suffer because of their use of social media and platforms that in turn deny responsibility for how people use them.
Over the next few weeks, the court will hear testimony from experts, family members of the deceased children, as well as Zuckerberg, Adam Mosseri, head of Instagra m, and Neil Mohan, CEO of YouTube.

The jury is also expected to hear from former Meta employees who resigned and became whistleblowers about the issue of children’s addiction to social media.
The outcome of the trial could be a benchmark for monetary compensation, and likely will be. Affecting thousands of cases brought by other plaintiffs, their families, state attorneys general and school districts across the United States.
In one such case brought by the attorneys general of 29 states, prosecutors have urged a California federal judge to order Meta to substantially modify or halt some of its business algorithms and platforms.
On Monday, all state attorneys general collectively requested an injunction requiring Meta to delete all accounts that
- Belong to users under the age of 13;
- Remove information the company has collected through Facebook and Instagram about users under 13;
- And remove artificial intelligence algorithms and generative tools that use such data.
A group of 18 state attorneys general who filed consumer protection lawsuits against Meta also filed a lawsuit asking the company to
- Impose temporary restrictions on young users, prohibiting use at school and at night;
- Disable addictive design features such as infinite scrolling and autoplay;
- And disable filters that enhance photos or the perception of beauty.

Meta has introduced certain features for “teen accounts” on Instagram over the past two years, including filtering content for users under 16.
On Monday, neither state nor lawyers argued that Meta’s actions were anything more than “a PR stunt that offers minimal real protection to teen users of the platforms.”
The lawsuit in Los Angeles was watched from the gallery by about a hundred parents who believe their children are dead because of the way social media companies have designed their algorithms, notifications and other features.
For their part, the companies say they are not responsible for content posted by third-party Parties.
Tellingly, Snap, the parent company of Snapchat, and TikTok last month reached a settlement with K. G. M. And are not defendants in the case, which was filed in Los Angeles Superior Court.
