Critically analyse the development from a broadcast culture to today’s so-called ‘participatory culture’.

Critically analyse the development from a broadcast culture to today’s so-called ‘participatory culture’. Focusing on key media and communications technologies, identify the factors that gave rise to the introduction and diffusion of these innovations, as well as the impact that these technologies have had on society.
Rather than discussing broadcast culture in isolation from participatory culture, try to identify continuities and similarities between these two epochs, while still acknowledging the distinctions.
