About the show

While Sliced Bread takes a break we serve up Toast. A study of the spectacular failures of brands which had promised so much to consumers. In each episode, the presenter and BBC business journalist Sean Farrington examines one big idea. What did it promise? Why did people back it? Why did they get burnt? Some of the world’s most successful businesses have also brought us some of the world’s most remarkable failures. So, what led them to be toast? And what can we learn from their stories today? Sean unpicks all the early optimism, hype and ambition. He learns about the tremendous success of a brand before hearing how it faltered, with help from expert commentators and people who were directly involved. How do they view things now and what, if anything, could have been done differently? The self-made millionaire and serial entrepreneur, Sam White, is alongside him, analysing the missteps that changed a brand’s fortunes and reaching her own, often instructive, conclusions. From big tech to high street retail and, of course, food, Toast tackles the business ideas that, one way or another, ended up cooked. Sliced Bread returns for a new batch of investigations in July, 2026. In the new series, Greg Foot will investigate more of the latest so-called wonder products to find out whether they really are the best thing since sliced bread. In the meantime, Toast is available in the Sliced Bread feed on BBC Sounds. Episodes will be released weekly on Thursdays wherever you get your BBC podcasts. But you can listen to the latest episodes, seven days earlier than anywhere else, first on BBC Sounds. Toast is a BBC Audio North production for BBC Radio 4.

Toast - EasyCinema

The EasyJet founder, Sir Stelios Haji-Iannou, tried to shake up the cinema industry by introducing low-cost movie theatres. Tickets were priced as low as 20p for customers who booked in advance. So, why didn't EasyCinema take off?Stelios speaks to the BBC Business journalist, Sean Farrington, reflecting on his attempts in the early 2000s to bring to UK cinemas the same dynamic pricing that had revolutionized the aviation sector. Sean also hears from Mark Batey (who was chief executive of the Film Distributors' Association when EasyCinema opened) and speaks to Stewart Niblock (who was Easy Group's Head of New Projects so was responsible for refurbishing and opening the cinema) and Angela Chan (who is now Professor of Creative Industries at Royal Holloway, University of London but in 2003 she was a BBC producer/director who was filming a TV documentary about EasyCinema).At the end, the resident business expert and entrepreneur, Sam White, has to come up with her own conclusions about the fate of EasyCinema based on what she has just heard.If you have a good idea for an interesting Toast topic then tell us about it - email toast@bbc.co.ukProduced by Jon Douglas, Toast is a BBC Audio North production for BBC Radio 4 and BBC Sounds.

Toast - Wilko

Wilkinson - or Wilko as it became known - was a privately-owned family business that had been successful for decades, offering low-priced household products from its chain of high street stores.

The BBC Business journalist, Sean Farrington, investigates how its stores ended up toast, in the company of resident business expert and entrepreneur, Sam White.To help explain what happened, Sean and Sam delve into the parliamentary archives and hear from expert guests including Gordon Brown who was Wilkinson's managing director for 15 years and Patrick O'Brien, Research Director at GlobalData who has followed the fortunes of high street names for over a decade. At the end, Sam has to come up with her own conclusions about the fate of Wilko based on what she has just heard.If you have a good idea for an interesting Toast topic then tell us about it - email toast@bbc.co.ukProduced by Jon Douglas, Toast is a BBC Audio North production for BBC Radio 4 and BBC Sounds.

Are infrared saunas as effective as traditional ones?If you've ever sat sweating on a wooden bench in a traditional ('Finnish') sauna wondering if there was an easier way, could infrared be the answer?
