I get the feeling that technologies like the internet have just shed light on the way people were already acting, as opposed to them influencing people to act trashier. What media technologies may have done though is influence people to do the same trashy things instead of their own different ones (e.g. little girls twerking).
Without the technology to make everything so easily transmittable, I don't think twerking becomes a thing like it has. Technology has played a role in the adoption of behaviors we see others do. Mass and social media creates phenomena now as opposed to juts shedding light on what was already happening.
