The world's richest companies are going head to head in a very public argument, one which effects both their bottom lines. It's all about profits. In one corner, there's Apple, not only the most dominant company in tech, but the highest valued business in the world. Its devices are in the hands of more than a billion people. In the other corner, Facebook. Its social media platform is used around the globe by close to three billion people. That reach gives it an extremly commanding hold on online advertising. And that's the problem. So, who will win in the end? Presenter: Peter Dobbie Guests Jim Anderson, C-E-O of Social Flow, a company that helps media organizations distribute its social content online. Joanna Bryson, Professor of Technology and Ethics at the Hertie School for Governance. Marc Owen Jones, professor who specializes in social media and the digital humanities at Hamad Bin Khalifa University. - Subscribe to our channel: aje.io/AJSubscribe - Follow us on Twitter: twitter.com/AJEnglish - Find us on Facebook: www.facebook.com/aljazeera - Check our website: www.aljazeera.com/ #AlJazeeraEnglish #InsideStory #Facebook #Apple
