Welcome to the explanation from the BBC World Service.
This is Ros Atkins and me, Katie Razzle, and this is the Media Show.
We're here to explain the trends behind the fast changing media landscape.
This week on the Media show, we'll speak to the journalist from the Times who's accompanied Ukrainian soldiers as they cross.
The border into Russia and the Korean TV industry.
From Squid Game to the Masked Singer, some of the most popular TV formats and shows in recent years have come from South Korea.
We'll find out why.
Let's start with Ukraine's offensive into the Russian region of Kursk.
This happened towards the beginning of August, and when it did, it was a surprise to many observers.
And of course, this has military objectives, but as well as that, it provides an opportunity for Ukraine to change the narrative around the war.
Catherine Philp is world affairs editor at the Times.
She's reported from war zones for decades and recently accompanied Ukrainian forces across the border into Kursk.
So I was coming into Ukraine for I've been coming on and off since before the invasion and this was a long scheduled visit.
It just so happened that it came at a time when Ukrainian forces had crossed the border into Russia.
So obviously my immediate question was, can we go?
Can we get there?
