Thanks for listening.

See you Monday.

So it is 6.30 a.m.

and it has just stopped raining.

I am waiting outside a courthouse trying to get into this trial that is happening today.

Yesterday morning, our colleague Megan Bobrowski was in Los Angeles.

She was there for a landmark trial and to watch testimony from a very high-profile witness.

Meta CEO Mark Zuckerberg is supposed to testify, and Mark Zuckerberg is going to be defending himself and the actions of his company today in court.

The key questions hanging over Zuckerberg's testimony?

Is social media designed to be addictive?

And is it harmful to teenagers?

Last week, the plaintiff's attorney, Mark Lanier, spoke about the case on Fox Business.

Lanier represents a 20-year-old woman who claims that she was harmed by social media use as a child.

Meta, which is the parent company of Facebook and Instagram, said in a statement prior to the trial's start that the plaintiff's lawyers will, quote, try to paint an intentionally misleading picture of Meta with cherry-picked quotes and snippets of conversations taken out of context.

This trial, which is being heard by a jury, is the first of its kind, and the first of thousands of similar cases that are expected to go to court in the coming years.

Here's Megan again.

These cases are focused on how Meta designed its apps and whether Meta designed its apps to be addictive to people.

That is a new argument that we're seeing.

So the outcome could fundamentally change how the company operates.

This could be a very big reckoning moment for big tech and social media might not ever look the same after this is said and done.
