Meta, YouTube and TikTok accused of making products intentionally addictive and harmful to young people

Jury selection starts this week in the Los Angeles County Superior Court.

A landmark case against social media giants Meta, Alphabet's YouTube and TikTok is set to begin Tuesday in Los Angeles Superior Court.

This marks the beginning of a legal onslaught that could erode Big Tech's longstanding defence.

Meta, Snap, TikTok and YouTube will face accusers in a series of lawsuits alleging that they intentionally design their platforms to be addictive.

TikTok has agreed to settle with a plaintiff and will no longer be part of a high-profile social media trial kicking off on Tuesday.
