Hello and welcome to the Intelligence, from the Economist. I'm Jason Palma.

And I'm Bora Ogambi. Every weekday we provide a fresh perspective on the events shaping your world.

Before this week, if you looked at the post-pandemic recovery of the world's big economies,

Britain looked to be the week one, but statisticians just released some reworked numbers and it's not too bad.

We ask how the story changed so much.

And in the era of apps, there's something nostalgic about using a real pocket calculator.

We have a summing up of its origins and its history.

But first.

So the other day I was watching this show called Citadel on Amazon Prime.

Tom Wainwright is the economist, technology and media editor.

And it's this spy thriller starring Priyanka Chopra Jonas.

In the opening scene you've got this amazing fight that goes on on a high speed train as it goes through the Alps in Italy.

She's in a shootout with loads of other spies.

It's really exciting, but if you pause the show, there's something really interesting at least to video nerds like me.

It gives you the option to buy more or less anything that you see in the program.

So you can buy Priyanka's red dress, you can buy her red stilettos, her gold chain that she's wearing.

You can't get by the exploding perfume, but you can buy pretty much anything else in the program.

Citadel is reckoned to have cost Amazon about $300 million to make, which is really expensive.

That makes it about the second most expensive TV show in history after rings of power, which was another Amazon show.

But the reception wasn't great. The critics didn't love it. The ratings weren't fantastic.

But the interesting thing is it may be that Amazon can make a pretty good business out of video without necessarily going down all that well with either critics or even with audiences.

But Tom, isn't getting lots of viewers and good reviews a marker of success?
