Facebook, Apple, Google, or Amazon. Dominant companies that today look unassailable. But similar claims were made about MySpace, Tesco, Microsoft, Kodak and Polaroid. However, these companies turned out to be more vulnerable than anyone thought. Evan Davis and guests discuss invulnerability, complacency and hubris in corporations.

Guests:

Evan Davis hosts the business conversation show.

The next generation of mobile technology - 5G - will be rolled out from 2019. It will enable faster streaming on our mobile phones and tablets and speed up the 'internet of things', allowing thousands of computers to 'talk' to each other. The fifth generation mobile network also has applications that could be used in public safety and healthcare. But will the UK build the infrastructure - installing more fibre and small communications masts - to benefit from this new technology? Joining Evan Davis for the debate will be:

Derek McManus, Chief Operating Officer at Telefonica UK, which owns O2.

The tech giant Apple has just spent five billion dollars building a campus in California's Silicon Valley. It's not alone in its architectural ambitions. The new Facebook HQ in London features trees, grass and plants. So what does a corporate headquarters tell us about a business? Is it an opportunity for a company to show off its wealth and attract the best talent or is it folly? Evan Davis and guests explore what the latest trends in corporate architecture reveal about our business leaders.

Guests:

What is strategy and why do businesses need it? What distinguishes a good strategy from a bad one or a non-strategy? Not to be confused with goals or a company's ambition, strategy is a word that is often mis-used and misapplied. But in reality it can make the difference between success and failure - especially if it's adaptable to changes in the market. Evan Davis looks at where companies have got strategy right and where it's gone badly wrong.
