What does it take to drill oil out of the ground and then refine it into petrol, jet fuel or other petrochemical products? The world currently uses about a hundred million barrels of oil a day. However, the daily flow has been affected by the closure of the Strait of Hormuz. A fifth of the global supply normally passes through the waterway in tanker ships, but it's been blocked since the end of February 2026. How has the industry adapted?

The 2026 London Marathon saw new world record times set in both the men's and women's events. Eyes weren't just on the winning athletes but also on the Adidas trainers they were wearing. So what goes into designing and making a pair of trainers and why have some of them become so expensive to buy? Global sales for trainers are in the tens of billions of dollars with hundreds of new styles being produced every year. How does the industry keep up with demand and stay on trend? Giant companies like Nike and Adidas, who dominated the industry for decades, can no longer take anything for granted. Newer brands like On and Hoka have managed to break through and are shaking things up. How have they managed to do it? Evan Davis gets some insights and answers from people who work in the industry.

From smartphones to trainers, confectionary and cleaning products, we live in a culture of constant updates. Companies reformulate, redesign and refresh their products in a continuous race to stay ahead. But how are those decisions made? What counts as meaningful improvement and how much is designed to make last year’s version feel old? Evan Davis and guests discuss how products evolve and why standing still is the fastest way to fall behind.

Across our professional careers, many of us will come into contact with a difficult colleague or hard-to-please superior. But what happens when difficult behaviour crosses over into bullying at work? What effect does this have, not only on our wellbeing, but on our workplace as a whole?

Evidence suggests that bullying may be on the rise in the UK. A 2025 survey of British workers conducted by ACAS (Advisory, Conciliation and Arbitration Service) found that 44% of respondents had experienced conflict at work in the last 12 months. And on the global stage, the resurgence of ‘strong man’ leadership has reignited a debate: does bullying behaviour get you what you want?

Evan and the panel look at what workplace bullying is, when and why bullying can occur, and the steps individuals and organisations can take to tackle this behaviour in the workplace.

The UK’s private rental market has grown dramatically over recent decades, creating what often feels like a tale of two nations: ‘Generation Rent’ who are priced out of home ownership and unable to access social housing; and buy-to-let investors who view property as a reliable income stream or pension plan.

Rising rents, poor conditions and fierce competition for homes have fuelled frustration with landlords, prompting political efforts to strengthen protections for tenants and increase tax pressure on property owners.

Now the sector is facing a turning point – with large institutional investors, backed by pension funds, for example, playing an increasing role. Evan Davis and guests discuss the state of the UK rental market and where it might be heading.

Everyone wants to get the best price they can when they buy, whether that’s a product, a service or an experience. But the ‘best price’ can look different for different people, and at different times.

Surge pricing, tiered prices, off-peak discounts, time-of-use pricing- technology has enabled more industries to employ dynamic pricing to get the best prices for their products by altering them depending on a range of sophisticated considerations.

But this has made pricing less predictable and left customers feeling like the prices are often stacked against them; most notably after the Oasis reunion tour ticket sales in 2024.

Is dynamic pricing really as bad as we all think? Evan and guests look at the psychology behind consumer perceptions of dynamic pricing, and ask how different industries can utilise the pricing model to benefit themselves and their customers.

From headline deals like Vodafone-Three or home builder, Barratt buying rival, Redrow, corporate mergers and takeovers are on the rise. Evan Davis and guests take a fresh look at what happens when companies combine. They discuss why deal-making is growing, why execs turn to M&A, what can go wrong and whether mergers deliver growth or simply disguise deeper problems.

In the years after the COVID pandemic we are travelling more and expecting more from our journeys. Travel is increasingly viewed as an end-to-end experience that begins before you even set foot on board your flight. As people look to inject luxury into their travel, airport lounge usage has boomed.

But lounges’ rise in popularity has created a unique problem for their operators: how do you grow your customer base whilst maintaining a degree of exclusivity?

Evan Davis speaks to industry operators and experts about balancing the scales.

Right now, Artificial Intelligence feels unstoppable. Investors are piling in, expectations are sky-high and claims about a radically different future are everywhere. To anyone who remembers the late 1990s, it all feels strikingly familiar.

Back then, the internet sparked the dotcom boom - a frenzy of big ideas, easy money and soaring valuations. When the bubble burst in 2000, billions were lost and companies wiped out. Yet the core idea proved right - the internet did transform lives, just more slowly and messily than expected. And there are important lessons to be learned.

Evan Davis talks to Ernst Malmsten, co-founder and CEO of boo.com, one of the most high-profile startups of the dotcom era. From his frontline seat in the boom and bust, he shares what really happened and what today’s AI moment can learn from it.
