The medium, or process, of our time - electric technology is reshaping and restructuring patterns of social interdependence and every aspect of our personal life. It is forcing us to reconsider and re-evaluate practically every thought, every action.

If old consumers were assumed to be passive, then new consumers are active. If old consumers were predictable and stayed where you told them, then new consumers are migratory, showing a declining loyalty to networks or media. If old consumers were isolated individuals, then new consumers are more socially connected. If the work of media consumers was once silent and invisible, then new consumers are now noisy and public.

When I wrote 'The World Is Flat,' I said the world is flat. Yeah, we're all connected. Facebook didn't exist; Twitter was a sound; the cloud was in the sky; 4G was a parking place; LinkedIn was a prison; applications were what you sent to college; and Skype, for most people, was a typo.

The function of entrepreneurs is to reform or revolutionize the pattern of production by exploiting an invention or, more generally, an untried technological possibility for producing a new commodity or producing an old one in a new way, by opening up a new source of supply of materials or a new outlet for products, by reorganizing an industry and so on.
