Some in the US are arguing for the break-up of Facebook, so we consider the arguments. Chris Hughes co-founded Facebook with Mark Zuckerberg, and believes the company's concentration of wealth, power and influence has become a threat to democracy. Dina Srinivasan is a digital advertising consultant, and former executive at the advertising agency WPP, and points to growing evidence that consumers are not happy with the level of tracking Facebook carries out on its users. We hear from Leslie Rutledge, attorney general for the state of Arkansas, which is one of 47 states which have come together to investigate whether Facebook's dominance has reduced users choices or increased the price of advertising. Meanwhile, Fiona Scott Morton, who used to work at the US Justice Department and is now an economist at the Yale School of Management argues that it might be quite tricky to force Facebook to sell off acquisitions like Instagram or WhatsApp. Also in the programme, our reporter Edwin Lane explores how easy it is to become an 'influencer' on social media. Plus we hear how a technology behind some of today's most popular film and video games, photogrammetry, has been around for over 150 years. Sam Jackson is co-founder of a British business which specialises in the technique, called Sample & Hold.
