And in general, gambling on sports isn't new, but what you are describing in this piece, and as you talk about all of the different apps, it feels categorically different from what most of us grew up understanding gambling to be, which is a trip to Vegas or March Madness, which we're in right now, or

A friendly bet with a friend or your brother, as you mentioned.

Something has changed.

Can you give us a sense of just how big this has gotten?

This all traces to several moments over the last few years, one going back to 2012.

Then New Jersey Governor Chris Christie signed the Sports Wagering Act, which was a state law that legalized sports betting at the state's casinos and racetracks.

The league took him to court and then the case landed in the Supreme Court.

is that the professional sports leagues, they fought this for years.

They even testified before Congress calling gambling an existential threat to sports.

The NFL and the NBA did.

And then the moment that the court ruled against them, they kind of ran towards the money.

Like how quickly did that reversal happen?

So I want to talk a little bit about maybe what could be called an integrity crisis, because while you were gambling your way through this NFL season, something else was happening simultaneously.

Walk us through what the FBI was uncovering, because it wasn't just one thing that they were looking at.

It was several scandals all at once.

Well, there seems to be a conflict of interest at the heart of this.

The leagues, the NFL, the NBA, the MLB, they now have financial stakes in the online betting platforms.

ESPN also once had its own betting operation.

I mean, these are institutions we're supposed to trust to keep the games clean.

And really, can they?
