And we are calling it iPhone.

Well, that was an announcement that would fundamentally change the way we all live.

And in his new documentary called 50 Years of Apple, my colleague and friend Bill Weir, he's going to look at how these devices we carry every day didn't just transform technology,

but they helped reshape our entire culture.

But for all the ways that these devices connect us and inform us and entertain us,

they're also probably rewiring us in ways that we're only beginning to understand.

I want to give you some stats quick,

and I'll just tell you that Bill's a father to two children. I have three girls, as many of you

know. Listen to these stats, especially if you're a parent, 40% of children have their own tablet

by age 2, 60% by age 4. This means that tablets are now one of the most common devices

children use under the age of 8, second only to the television. That's remarkable. These

devices didn't even exist when we were kids, and now they are the most common devices that

children use.

So what is all of that doing to our brains? What does that rewiring really mean?

Today, we're going to dive deep into what Bill has uncovered in this documentary project

that he's been working on. And I think also importantly, what really works if you say, hey, look, this is a problem

for me. This is a problem for my children. What really works in terms of helping you break that

habit? I'm Dr. Sanjay Gupta, and this is chasing life.

I'd love to catch up with you sometime and hear about life in general, but I'm dying to know about this documentary.

Okay.

Fifty years of Apple.

First of all, I think, Bill, most people know you obviously as the chief climate guy.
