Here in the U.S., big business has done its fair share of mind programming; getting the populous to believe that their product of business is safe, healthy, the best, etc. In addition, politicians have used similar techniques, and sow seeds of doubt about their opponents. It has not stopped there. Unions, courts, schools, activist groups (both moderate and extreme) have all campaigned to promote their own interests, while simultaneously undermining their opposition.
Recently, Sacha Baron Cohen labelled social media, "the greatest propaganda machine in history." He elaborated that, "All this hate and violence is being facilitated by a handful of internet companies that amount to the greatest propaganda machine in history."
Oh the irony!
