The U.S. state of Alabama announced on the 25th that it has reached a settlement with the video-sharing app TikTok and its parent company, China's ByteDance, over the harmful effects on teenage users' mental health. Under the terms of the settlement, TikTok will pay the state at least $100 million, but the amount paid to Alabama could grow to as much as $300 million if attorneys general from 40 other states sign similar agreements within a specified period. The company will be required to impose a two-hour daily usage limit on teenage users in Alabama, interrupt usage every 15 minutes, and adopt stricter age verification. This is the first time TikTok has settled with a state in the broad litigation over social media's impact on teen mental health, with at least 27 other states and Washington, D.C., having filed similar lawsuits. The settlement applies only to Alabama, but making large-scale platform changes state by state may prove difficult.
