//HyperNormalisation is a 2016 BBC documentary by British filmmaker Adam Curtis. In the film, Curtis argues that since the 1970s, governments, financiers, and technological utopians have given up on the complex "real world" and built a simple "fake world" that is run by corporations and kept stable by politicians.//
