Business Matters: $11bn Online Ad Fraud 14 Aug 14

Thu, 14 Aug 14

As much as 50% of online ads are never viewed by humans, rather they're 'clicked' by bots - scam software designed to mimic¹ human activity and defraud² the advertisers. Ari Levenfeld from agency Rocket Fuel lifts the lid on a murky³ and complex world. Andrew Walker takes to the streets of London to explain the perils⁴ of deflation - now a threat in the Eurozone. Prize-winning author and journalist, and renowned⁵ Cuba expert Ann Louise Bardach joins us on Fidel Castro's 88th birthday to discuss the future of the isolated⁶ Caribbean island. Plus, Emma Ostergren joins us from Sweden to explain the thinking behind her firm Emma O Clothing, from which 60% of profit goes to its workers in Zimbabwe.
