what the world was like 40 years ago. No one knew about it. 
we have been talking about the ideas in this conference . its about can you get your ideas spread or not. what we are living in is the century of ideas . 
if you could spread these ideas , they will win and its regardless of what these ideas are.
***
at the heart of spreading ideas is TV and mass media . TV & mass media made it too easy to spread the idea.
