Welcome to Business Daily on the BBC World Service. I'm Frey Lindsay.

Hello.

Hey, how you going?

Yeah, fine.

This is my friend Danny. He's just gotten back from a long holiday in Japan.

About 10 years ago, Danny and I were going around record stores in Tokyo.

In one of these stores, we picked up a free mixtape CD that they were just kind of giving out.

I think you were given the mixtape.

And yeah, it was just this really carefully crafted selection of 60s,

spoky sort of pop music. All of the tracks were just these really rare finds. A lot of those

tracks ended up playing quite an important part in our lives. Eventually, we lost the physical

CD, and I've long since lost the digital copies that we made. Do you remember last time we were in Japan,

I was convinced that I had found that record store and we went back there. And I said 10 years ago,

we came and we got this CD. Can we have another one? And they said, you've got the wrong store.

We weren't open 10 years ago. That was pretty

devastating. We've all got a story like this, right? Some piece of media, some childhood

drawing or a letter that you sent when you were young, something that's one of a kind and

that you'd give anything to get back. These things are like little markers of who we used to be,

and they lead us to who we are now. They're a big part of our history. And that's what this episode

of Business Daily is about, but writ large, because we're talking today about how for many of us,

so much of those memories are stored online. So I've been blogging for a quarter of a century,

and that means that I've got tens of thousands of old blog posts going back to the early 2000s.
