This thorough Frontline exploration of the Big Tech firms that are increasingly influencing our everyday lives shows both the public benefits of Jeff Bezos' innovations and how such unprecedented corporate power needs a counter-acting force. Amazon has drawn criticism on several major fronts - from alleged privacy violation, to unsafe workplaces, to driving small businesses to the wall - because it is such a sprawling, multidimensional enterprise. Frontline producers are fair in giving a great many Amazon executives as much airplay as the company's critics, and Amazon was p.r.-wise in making them available and accountable. All in all, a good, well-rounded look at a business phenomenon which, with its Big Business counterparts, deserve careful thought on how we are to reap the benefits of their innovation and protect against the side-effects. It's worth noting with these larger-than-life companies - Facebook, Walmart, Microsoft, Amazon - that always they become so big that they simply cannot self-police, try as they do, without external direction and occasional restraint.
