The Century of the Self: A documentary about how we came to be the consumer society that we are today. Adam Curtis tells the story of what made this western consumer society come to be and also looks into what choices we make and why we make them.
It started in the 19th century with Edward Bernays who is the nephew of Sigmund Fred. He was a marketing specialist who devised the idea behind the driving force of people wanting things that they didn't need consciously.
This idea stuck and through the twentieth century it had expanded from only marketing products to actually being an element of how contemporary politics works. The idea was that people should not make their own choices but rather be guided to make conclusions based on the guidance from renowned people.
In 2015 it seems like this idea has practically come full circle and that political agendas are based on what voters want to hear.
