Bandwidth Sync Correlation & Media

(reproduced from Seth Godin's blog, including the text)

So, what can you learn here?

1. There's a huge correlation between how much interaction there is and how powerful a medium is (at least among successful media). Telephones changed the world because the interaction is so real. As you get more interactive, though, you exchange less dense media. You can't have a real time conversation online that carries the digital impact of a movie or some other high bandwidth entertainment.
2. The bottom left corner is the scrap heap. It's hard to place a commercial value on this part of the grid and there's not a lot of commercially interesting work being done here. People just aren't interested in low bandwidth, non-interactive media. Graffiti, for example, rarely draws a paying crowd.
3. The top right of the corner is where huge value and difficult sales lie. Not everyone can pay for the scarce resources needed to deliver an in-person seminar or one on one coaching, but those that need and can afford it, love it.

If you had seen this chart three years ago, you obviously would have invented Twitter. Now that you see it today, what will you create?
