One month after a judge declared Google's search engine an illegal monopoly, the tech giant faces another antitrust lawsuit that threatens to break up the company, this time over its advertising technology.

The Justice Department, joined by a coalition of states, and Google each made opening statements Monday to a federal judge who will decide whether Google holds a monopoly over online advertising technology, The AP reported.

The regulators contend that Google built, acquired and maintains a monopoly over the technology that matches online publishers to advertisers. Dominance over the software on both the buy side and the sell side of the transaction enables Google to keep as much as 36 cents on the dollar when it brokers sales between publishers and advertisers, the government contends in court papers.

They allege that Google also controls the ad exchange market, which matches the buy side to the sell side.

“It's worth saying the quiet part out loud,” Justice Department lawyer Julia Tarver Wood said during her opening statement. “One monopoly is bad enough. But a trifecta of monopolies is what we have here.”

Google says the government's case is based on an internet of yesteryear, when desktop computers ruled and internet users carefully typed precise World Wide Web addresses into URL fields. Advertisers now are more likely to turn to social media companies like TikTok or streaming TV services like Peacock to reach audiences.

In her opening statement, Google lawyer Karen Dunn said, “We are one big company among many others, competing millisecond by millisecond for every ad impression.”

Revenue has actually declined in recent years for Google Networks, the division of the Mountain View, California-based tech giant that includes such services as AdSense and Google Ad Manager that are at the heart of the case, from $31.7 billion in 2021 to $31.3 billion in 2023, according to the company's annual reports.

The trial that began Monday in Alexandria, Virginia, over the alleged ad tech monopoly was initially going to be a jury trial, but Google maneuvered to force a bench trial, writing a check to the federal government for more than $2 million to moot the only claim brought by the government that required a jury.

The case will now be decided by US District Judge Leonie Brinkema, who was appointed to the bench by former President Bill Clinton and is best known for high-profile terrorism trials including that of Sept. 11 defendant Zacarias Moussaoui. Brinkema, though, also has experience with highly technical civil trials, working in a courthouse that sees an outsize number of patent infringement cases.

The Virginia case comes on the heels of a major defeat for Google over its search engine, which generates the majority of the company's $307 billion in annual revenue. A judge in the District of Columbia declared the search engine a monopoly, maintained in part by tens of billions of dollars Google pays each year to companies like Apple to lock in Google as the default search engine presented to consumers when they buy iPhones and other gadgets.

In that case, the judge has not yet imposed any remedies. The government hasn't offered its proposed sanctions, though there could be close scrutiny over whether Google should be allowed to continue to make exclusivity deals that ensure its search engine is consumers' default option.

Peter Cohan, a professor of management practice at Babson College, said the Virginia case could potentially be more harmful to Google because the obvious remedy would be requiring it to sell off parts of its ad tech business that generate billions of dollars in annual revenue.

“Divestitures are definitely a possible remedy for this second case,” Cohan said “It could be potentially more significant than initially meets the eye.”

In the Virginia trial, the government's witnesses are expected to include executives from newspaper publishers including The New York Times Co. and Gannett, and online news sites that the government contends have faced particular harm from Google's practices.

“Google extracted extraordinary fees at the expense of the website publishers who make the open internet vibrant and valuable,” government lawyers wrote in court papers. “As publishers generate less money from selling their advertising inventory, publishers are pushed to put more ads on their websites, to put more content behind costly paywalls, or to cease business altogether.”

Google disputes that it charges excessive fees compared to its competitors. The company also asserts the integration of its technology on the buy side, sell side and in the middle assures ads and web pages load quickly and enhance security. And it says customers have options to work with outside ad exchanges.

Google says the government's case is improperly focused on display ads and banner ads that load on web pages accessed through a desktop computer and fails to take into account consumers' migration to mobile apps and the boom in ads placed on social media sites over the last 15 years.

The government's case “focuses on a limited type of advertising viewed on a narrow subset of websites when user attention migrated elsewhere years ago,” Google's lawyers wrote in a pretrial filing. “The last year users spent more time accessing websites on the ‘open web,’ rather than on social media, videos, or apps, was 2012.”

The trial, which is expected to last several weeks, is taking place in a courthouse that rigidly adheres to traditional practices, including a resistance to technology in the courtroom. Cellphones are banned from the courthouse, to the chagrin of a tech press corps accustomed at the District of Columbia trial to tweeting out live updates as they happen.

Even the lawyers, and there are many on both sides, are limited in their technology. At a pretrial hearing Wednesday, Google's lawyers made a plea for more than the two computers each side is permitted to have in the courtroom during trial. Brinkema rejected it.

“This is an old-fashioned courtroom,” she said.

Comparing social media platforms to casinos and addictive drugs, lawyer Mark Lanier delivered opening statements Monday in a landmark trial in Los Angeles that seeks to hold Instagram owner Meta and Google's YouTube responsible for harms to children who use their products.

Instagram's parent company Meta and Google's YouTube face claims that their platforms addict children through deliberate design choices that keep kids glued to their screens. TikTok and Snap, which were originally named in the lawsuit, settled for undisclosed sums.

Jurors got their first glimpse into what will be a lengthy trial characterized by dueling narratives from the plaintiffs and the two remaining defendants.

Meta lawyer Paul Schmidt spoke of the disagreement within the scientific community over social media addiction, with some researchers believing it doesn’t exist, or that addiction is not the most appropriate way to describe heavy social media use.

‘Addicting the brains of children’

Lanier, the plaintiff's lawyer, delivered lively first remarks where he said the case will be as “easy as ABC” — which stands for “addicting the brains of children.” He said Meta and Google, “two of the richest corporations in history,” have “engineered addiction in children’s brains.”

He presented jurors with a slew of internal emails, documents and studies conducted by Meta and YouTube, as well as YouTube’s parent company, Google. He emphasized the findings of a study Meta conducted called “Project Myst” in which they surveyed 1,000 teens and their parents about their social media use.

The two major findings, Lanier said, were that Meta knew children who experienced “adverse events” like trauma and stress were particularly vulnerable for addiction; and that parental supervision and controls made little impact.

He also highlighted internal Google documents that likened some company products to a casino, and internal communication between Meta employees in which one person said Instagram is “like a drug” and they are “basically pushers.”

At the core of the Los Angeles case is a 20-year-old identified only by the initials “KGM,” whose case could determine how thousands of other, similar lawsuits against social media companies will play out. She and two other plaintiffs have been selected for bellwether trials — essentially test cases for both sides to see how their arguments play out before a jury.

Plaintiff grew up using YouTube, Instagram

KGM made a brief appearance after a break during Lanier’s statement and she will return to testify later in the trial. Lanier spent time describing KGM's childhood, focusing particularly on what her personality was like before she began using social media.

She started using YouTube at age 6 and Instagram at age 9, Lanier said. Before she graduated elementary school, she had posted 284 videos on YouTube.

The outcome of the trial could have profound effects on the companies' businesses and how they will handle children using their platforms.

Lanier said the companies’ lawyers will “try to blame the little girl and her parents for the trap they built,” referencing the plaintiff. She was a minor when she said she became addicted to social media, which she claims had a detrimental impact on her mental health.

Lanier said that despite the public position of Meta and YouTube being that they work to protect children, their internal documents show an entirely different position, with explicit references to young children being listed as their target audiences.

The attorney also drew comparisons between the social media companies and tobacco firms, citing internal communication between Meta employees who were concerned about the company’s lack of proactive action about the potential harm their platforms can have on children and teens.

“For a teenager, social validation is survival,” Lanier said. The defendants “engineered a feature that caters to a minor’s craving for social validation,” he added, speaking about “like” buttons and similar features.

Meta pushes back

In his opening statement representing Meta, Schmidt said the core question in the case is whether the platforms were a substantial factor in KGM’s mental health struggles. He spent much of his time going through the plaintiff’s health records, emphasizing that she had experienced many difficult circumstances in her childhood, including emotional abuse, body image issues and bullying.

Schmidt presented a clip from a video deposition from one of KGM‘s mental health providers, Dr. Thomas Suberman, who said social media was “not the through-line of what I recall being her main issues,” adding that her struggles seemed to largely stem from interpersonal conflicts and relationships.

He painted a picture — with KGM’s own text messages and testimony pointing to a volatile home life — of a particularly troubled relationship with her mother.

Schmidt acknowledged that many mental health professionals do believe social media addiction can exist, but said three of KGM’s providers — all of whom believe in the form of addiction — have never diagnosed her with it, or treated her for it.

Schmidt stressed to the jurors that the case is not about whether social media is a good thing or whether teens spend too much time on their phones or whether the jurors like or dislike Meta, but whether social media was a substantial factor in KGM’s mental health struggles.

A reckoning for social media and youth harms

A slew of trials beginning this year seek to hold social media companies responsible for harming children's mental well-being. Executives, including Meta CEO Mark Zuckerberg, are expected to testify at the Los Angeles trial, which will last six to eight weeks.

Experts have drawn similarities to the Big Tobacco trials that led to a 1998 settlement requiring cigarette companies to pay billions in health care costs and restrict marketing targeting minors.

A separate trial in New Mexico, meanwhile, also kicked off with opening statements on Monday. In that trial, Meta is accused of failing to protect young users from sexual exploitation, following an undercover online investigation. Attorney General Raúl Torrez in late 2023 sued Meta and Zuckerberg, who was later dropped from the suit.

A federal bellwether trial beginning in June in Oakland, California, will be the first to represent school districts that have sued social media platforms over harms to children.

In addition, more than 40 state attorneys general have filed lawsuits against Meta, claiming it is harming young people and contributing to the youth mental health crisis by deliberately designing features on Instagram and Facebook that addict children to its platforms. The majority of cases filed their lawsuits in federal court, but some sued in their respective states.

TikTok also faces similar lawsuits in more than a dozen states.


AI No Better Than Other Methods for Patients Seeking Medical Advice, Study Shows

Asking AI about medical symptoms does not help patients make better decisions about their health than other methods, such as a standard internet search, according to a new study published in Nature Medicine.

The authors said the study was important as people were increasingly turning to AI and chatbots for advice on their health, but without evidence that this was necessarily the best and safest approach.

Researchers led by the University of Oxford’s Internet Institute worked alongside a group of doctors to draw up 10 different medical scenarios, ranging from a common cold to a life-threatening hemorrhage causing bleeding on the brain.

When tested without human participants, three large-language models – Open AI's Chat GPT-4o, ‌Meta's Llama ‌3 and Cohere's Command R+ – identified the conditions in ‌94.9% ⁠of cases, ‌and chose the correct course of action, like calling an ambulance or going to the doctor, in an average of 56.3% of cases. The companies did not respond to requests for comment.

'HUGE GAP' BETWEEN AI'S POTENTIAL AND ACTUAL PERFORMANCE

The researchers then recruited 1,298 participants in Britain to either use AI, or their usual resources like an internet search, or their experience, or the National Health Service website to ⁠investigate the symptoms and decide their next step.

When the participants did this, relevant conditions were identified in ‌less than 34.5% of cases, and the right ‍course of action was given in ‍less than 44.2%, no better than the control group using more traditional ‍tools.

Adam Mahdi, co-author of the paper and associate professor at Oxford, said the study showed the “huge gap” between the potential of AI and the pitfalls when it was used by people.

“The knowledge may be in those bots; however, this knowledge doesn’t always translate when interacting with humans,” he said, meaning that more work was needed to identify why this was happening.

HUMANS OFTEN GIVING INCOMPLETE INFORMATION

The ⁠team studied around 30 of the interactions in detail, and concluded that often humans were providing incomplete or wrong information, but the LLMs were also sometimes generating misleading or incorrect responses.

For example, one patient reporting the symptoms of a subarachnoid hemorrhage – a life-threatening condition causing bleeding on the brain – was correctly told by AI to go to hospital after describing a stiff neck, light sensitivity and the "worst headache ever". The other described the same symptoms but a "terrible" headache, and was told to lie down in a darkened room.

The team now plans a similar study in different countries and languages, and over time, to test if that impacts AI’s performance.

The ‌study was supported by the data company Prolific, the German non-profit Dieter Schwarz Stiftung, and the UK and US governments.

Meta Platforms on Monday criticized EU regulators after they charged the US tech giant with breaching antitrust rules and threaten to halt its block on ⁠AI rivals on its messaging service WhatsApp.

"The facts are that there is no reason for ⁠the EU to intervene in the WhatsApp Business API. There are many AI options and people can use them from app stores, operating systems, devices, websites, and ⁠industry partnerships," a Meta spokesperson said in an email.

"The Commission's logic incorrectly assumes the WhatsApp Business API is a key distribution channel for these chatbots."
