Why do some big successful brands go bust?

Toast is back for a new series, taking a look at the decisions that often left investors burnt.

I'm Sean Farrington, a BBC business journalist. I'll be hearing about the hype.

They're going to do the deal that makes them the most money at that point of time.

And I'm picking what went wrong, talking to

owners and employees to ask what can we learn. It was being undercut by similar rivals. It just

couldn't survive. Toast. Listen first on BBC Sounds. BBC Sounds, music, Radio, podcasts.

Hi, I'm Kirsty Young, and this is Young again, my podcast for BBC Radio 4.

What conversations would you have with your younger self? How'd you reflect on the big decisions you've made? What have you learned from your life so far? On this episode of Young Again, I'm talking with an actor and writer whose most notable comedy creation stands alongside Basil Faulty and David Brent as one of TV's greats. And yet, it occurred to me as we chatted that much of his other work,

rather than making us laugh, is actually about making us think. We met up in a month that

seems to perfectly illustrate the breadth of his talent, with the release of his landmark drama

on the sexual predator Jimmy Saville, followed weeks later by the publication of Alan Partridge's latest spoof memoir.

In this edition of Young Again, I'm in conversation with the dazzlingly versatile Steve Coogan.

Steve, it strikes me this is quite an unusual few months in your life.

You've just had a lot of attention for playing the character of Jimmy Saville in a major BBC drama

to huge acclaim, unsurprisingly, and you are also now talking to us about Alan Partridge's memoir.

Is it an odd existence?

Yes, it is odd, and it could be quite awkward.

So I've tried to avoid those two things bumping into each other.

Probably about 10 years ago I started doing more dramatic stuff.

But I didn't want to stop doing comedy.

I just wanted to do, you know, like most people, I want to do everything.
