Alternative media is much more productive in my opinion. Timothy Leary and Marshall McCluhan come to mind.
Then came Marshall McCluhan, in the 1950's. McCluhan said, in the Socratic sense, "The medium is the message." The words you use, the modes of communication you use determine the realities you inhabit. Most of our lives, most of us live in realities determined by others, imprinted in our brains by education, by religion, by politics, by the authorities. McCluhan said, "If you want to change your mind, change the medium." Change the words you use. Change the mode of communication. If you change the medium, you change yourself. You change your society.
