The fashion chain C&A continues to thrive elsewhere so why did it shut all its UK stores?

The BBC Business journalist, Sean Farrington, investigates how they ended up toast, in the company of resident business expert and entrepreneur, Sam White.

C&A used to be one of the biggest fashion retailers on the UK's high streets until a shock decision in 2000 led to the stores' sudden closure.

To help explain what happened, Sean and Sam delve into the BBC archives and hear from expert guests including Donna Bevan - fashion historian, lecturer and course leader at the School of Creative Industries at Southampton Solent University and Stephen McDermott who worked at C&A for 35 years.

Produced by Jon Douglas, Toast is a BBC Audio North production for BBC Radio 4 and BBC Sounds.

Why did Skype fall out of favour in a world of global video calls?

The BBC Business journalist, Sean Farrington, investigates with the entrepreneur, Sam White, alongside him.

Sam never knows what's coming so, at the end of every episode of Toast, she gives her off-the-cuff and authentic professional opinions on why a brand disappeared based on what she has just heard and her own business knowhow.

In this episode, we learn how Skype worked by using Voice Over Internet Protocol to send audio and video data over the internet. It connected users through a centralized, cloud-based service which allowed free voice and video calls between Skype users.

It really changed the game when it came to keeping in touch with friends and family around the world. It helped grandparents meet their grandchildren for the first time without leaving the house and gave us a way of cutting our phone bills.

Sean interviews:

- Peter Raeburn - an award-winning composer who worked with Skype’s founders to create the iconic sounds that became the familiar sound track to Skype which, at its peak, was used by over 300 million people worldwide.

- Andrew Sinclair - a General Manager for Skype for Business who offers his insight into what happened after Skype was sold by Ebay, and snapped up by tech giant, Microsoft.

-Sam Shead - a journalist who witnessed how Skype changed the world of communication, soaring and then sinking and has taken an in depth look at the names behind the brand, so what did he uncover?

Produced by Linda Walker.

Dasani water, a bottled water from Coca-Cola, proved a big hit in the U.S.A so why did it last for less than 6 weeks in the UK?

The BBC Business journalist, Sean Farrington, investigates how it ended up toast, in the company of resident business expert and entrepreneur, Sam White.

In the early 2000s, Coca-Cola had entered the growing bottled water market and was hoping to turn its hit new brand in America into a global sensation.

But shortly after Dasani water was launched in the UK, things quickly went awry, derailing plans for expansion into Europe.

To help explain what happened, Sean and Sam delve into the BBC archives and hear from expert guests including Graham Hiscott, the journalist whose story shone a new light on to the brand, and Conor Carroll a lecturer and marketing expert who has written about the Dasani debacle.

They also hear from Toast listener, Chris Leversha, who remembers buying Dasani water and suggested we cover it on the show.

At the end, Sam has to come up with her own professional conclusions about the fate of Dasani UK based on what she has just heard.

How did the company behind the revolutionary BlackBerry smartphone lose its grip on the handset market?

The BBC Business journalist, Sean Farrington, investigates with special guest, Sir Stephen Fry, who has remained 'faithful' to the BlackBerry brand.

Alongside them is the entrepreneur, Sam White, who at the end of the show has to reach her own conclusions on why BlackBerry handsets disappeared, based only on what she has just heard and her own business acumen.

The first BlackBerry device freed business executives from their desks, allowing them to easily write, send and receive emails from almost anywhere. But that was not the only thing that made the BlackBerry, and its later iterations, extraordinary.

The actor, comedian, author and broadcaster, Sir Stephen Fry, also used to be a tech blogger and wrote in glowing terms about BlackBerry devices...until they took a turn for the worse.

Stephen explains why he was disappointed by a brand he loves and how he still hopes it might make a return.

Jim Balsillie was a co-chief executive officer at Research in Motion, the company that created BlackBerry, and offers his insight into how it quickly became a $20billion business and why he felt compelled to resign from such a tremendously successful venture.

The entrepreneur and tech blogger, Kevin Michaluk, witnessed how BlackBerry handsets soared and then sank. He's made a successful career out of building "spiritual successors" to them but can his attempts to bring them back under the original brand prove successful?

The podcast version of this episode, available on BBC Sounds, includes a bonus interview at the end with Sir Stephen Fry on how he feels about technology and social media today.
