A lawsuit concerning youth social media overdependence and mental health issues in the U.S. has entered a new phase.

A lawsuit filed by the Breckinridge County School District in Kentucky against major social media companies, including Meta, Alphabet (YouTube's operator), Snap (Snapchat's operator), and ByteDance (TikTok's operator), is expected to be settled out of court just before trial.

This case was designated as a lead trial among similar lawsuits filed by approximately 1,200 school districts nationwide. The school districts argued that the design and operational methods of social media companies exacerbated mental health problems in adolescents, such as anxiety, depression, and self-harm, and that the repercussions led to increased burdens on school counseling, treatment, and guidance services.

The terms of the settlement have not been disclosed, and a settlement does not necessarily imply an admission of responsibility. However, it is clear that U.S. school districts have begun to hold platform companies accountable for the burdens placed on schools.

Questions Raised by the U.S. Lawsuit

This case should not be viewed as merely an overseas IT lawsuit.

South Korea is approaching superintendent elections alongside the 9th National Simultaneous Local Elections on June 3rd. Superintendents are educational administrators who directly influence on-site school guidance, student mental health support, digital learning environments, and policies for managing smart devices in schools.

Therefore, the questions voters should ask in this election should also change.

Is it enough to simply collect students' mobile phones during class hours? To what extent will educational administration responsibly address the platform structures that continuously captivate adolescents, such as short-form content, recommendations, notifications, DMs, open chats, and live chat?

South Korea has already begun implementing in-classroom measures.

Starting March 2026, the use of smart devices, including smartphones, during class will be prohibited in principle. Amendments to the Elementary and Secondary Education Act have established a legal basis for schools to restrict the use and possession of smart devices within school premises to protect students' right to learn and ensure teachers' educational activities. Exceptions, such as the use of assistive devices by students with disabilities and use for educational purposes, are also stipulated.

However, this measure addresses only half of the problem.

Restricting smartphone use during class can serve as a device to restore order in the classroom.

However, adolescents' digital overdependence does not occur solely within the classroom.

It continues after school, after returning home, late at night, on weekends, within group chats, open chats, short-form feeds, live chats, DMs, and notification structures. Temporarily taking smartphones out of students' hands is a different issue from examining the platform structures that keep students hooked.

The Reality Revealed by High-Risk Group Statistics

The 2025 Youth Media Use Habit Diagnosis Survey, released by the Ministry of Gender Equality and Family, illustrates the scale of the problem.

Among the 1,234,587 participants in the survey of 4th graders, 1st-year middle school students, and 1st-year high school students, 213,243 were identified as being at risk of internet and smartphone overdependence.

The government explained that this survey aims to identify adolescents struggling with media overdependence early on to help them heal and recover.

This suggests that South Korea is already treating youth media overdependence not as a personal habit issue but as a problem requiring public support.

However, identifying at-risk groups is different from questioning the environments that foster risk.

Current policies are closer to a reactive system where counseling is provided after a student becomes at-risk, schools provide guidance, parents control usage, and the government supports healing programs.

In other words, while a post-response system is being established, public questions about the platform structures that push adolescents toward overdependence are still insufficient.

Youth Media Consumption Shifts to Short-Form Content

Data from the Korea Press Foundation further clarifies the issue.

According to the "2025 Survey on Media Use by Teenagers" report by the Korea Press Foundation, released on January 7th, 95.1% of teenagers used online video platforms in the past week. (Survey Institution: Korea Gallup, Survey Period and Target: June-September 2025, 2,674 students from 4th grade elementary to 3rd grade high school).

The average daily viewing time was 200.6 minutes, approximately 3.3 hours. The most frequently used platforms, in order, were Instagram Reels, YouTube, YouTube Shorts, TikTok, and Naver Clip.

This point is crucial. While the Ministry of Gender Equality and Family's statistics show the scale of at-risk youth, the Press Foundation's survey reveals how the structure of youth media consumption is changing.

The problem is not simply watching smartphones for extended periods.

It combines short-form content that provides continuous, intense stimuli, recommendation algorithms that track user interests to push the next video, notifications that constantly lure users back, and DM and group chat structures that tie peer relationships and private conversations within the platform.

We have entered a stage where it is not adolescents using platforms, but platforms organizing adolescents' time.

Overseas Regulations Shift Towards Platform Responsibility

A policy report from the Korea Press Foundation also points in the same direction.

In its Media Issue Report 2026, Issue 2, "Overseas Regulatory Trends for Responding to Smartphone and Social Media Overdependence in Children and Adolescents," published on March 6, 2026, the foundation summarized the regulatory trends in major countries such as the U.S., the UK, France, and Australia.

The report presented the direction of overseas regulations as three pillars: strengthening platform responsibility, institutionalizing age-based systems, and expanding parental support and education.

This indicates that the issue of adolescent smartphone and social media overdependence is no longer confined to individual self-regulation or parental education, but is shifting to a matter of platform design and operation methods and public regulation.

This is also the significance of the U.S. school district lawsuit.

U.S. school districts are not simply raising the issue of "students using social media too much." They are asking in court whether the design and operational methods of social media companies have increased student mental health issues and the burden of response on schools.

The focus is on the structure, not individual content.

Infinite feeds, recommendation algorithms, notifications, account retention mechanisms, the effectiveness of parental controls, and protections for minors can all become subjects of concern.

Questions the Superintendent Elections Must Answer

South Korea's superintendent elections cannot evade these questions either.

It is insufficient for superintendent candidates to simply state whether they are for or against restricting student smartphone use.

There are more important questions.

"To what extent do each of the education offices precisely grasp the status of youth digital overdependence at the school level?

Are they linking statistics on classroom disruption, cyberbullying, harm from open chats and DMs, short-form content addiction, and late-night notifications with guidance and counseling statistics?

Do they plan to demand that platform companies strengthen default settings for minor protection, limit nighttime notifications, implement usage restrictions during school hours, and improve parental control features?"

Of course, whether South Korean education offices can immediately file lawsuits like those in the U.S. is a separate issue.

They must prove damages and causality, and legally contest whether the burden of counseling, treatment, and guidance in education offices was caused by the design and operational methods of specific platforms.

However, what is needed before the possibility of lawsuits is the framing of the problem.

The priority is whether educational administration will view this issue solely as a lack of self-control by students or a problem of parental education, or whether it will be treated as a public agenda that includes the impact of platform structures on schools.

The issues in Korea are not entirely the same as those in the U.S.

While the U.S. lawsuits center on Facebook, Instagram, YouTube, Snapchat, and TikTok, in Korea, we must also consider global platforms along with KakaoTalk open chats, Instagram DMs, Naver Clip, live chats, webtoon/web novel platforms, and gaming/streaming platforms.

In particular, peer relationships among Korean youth are formed and conflicts are amplified through messengers, group chats, open chats, and DMs.

Cyberbullying, anonymous contact, sexual solicitation, excessive notifications, and short-form content addiction are not separate issues but are interconnected within a single digital living environment.

Superintendent elections are not elections held solely based on textbooks, school lunches, and school facilities.

Today's schools have already expanded into the platform space.

Outside the classroom, students continue their peer interactions and information consumption within group chats, short-form content, live chats, anonymous communities, and recommended feeds. The overdependence, conflicts, bullying, and anxiety that occur there return to the classroom.

Ultimately, although school sites may seem to be outside the platform, they are, in reality, spaces that process the effects of platforms daily.

Now, superintendent candidates must answer.

"Is collecting students' mobile phones enough?

Is simply increasing counseling and healing programs enough?

What standards will educational administration demand from platform companies that design adolescents' time, mediate relationships, and capture their attention?"

The U.S. school district lawsuit poses a question before the South Korean superintendent elections.

"Will we leave digital issues for adolescents as a post-hoc burden for schools and families, or will we expand educational policies to include platform responsibility?"
