The media landscape has changed over time from the printing press to the telephone to radio waves that allowed TV and radio.  However, the internet is the first source of media that gives us the man-to-many conversation pattern, rather than the one-to-one pattern of the phone, or the one-to-many pattern of radio and television.  Everyone is a listener, everyone is a producer – it’s like having a phone that could turn into a radio if you pushed the right buttons.  Listen to Clay Shirky as he addresses how this powerful paradigm shift has affected how we receive news – from all around rather than the top down – and how that affects the workings of the world and the politics within it.  This is an amazing talk about the power of social media, and the power that social media endows people with.
