Fun with Wikipedia

Check out this article on the history of printing in the Wikipedia.

Think about it; It took 3200 years for humans to advance from the use of Cuneiform, where letters are cut into clay tablets with a stylus, to the invention of woodblock printing, where images are carved in relief. Another 840 years would pass before the use of movable type by the Chinese and Koreans. The mechanical printing press took almost 400 years more. The next advance in publishing took another 357 years. In all, the average time to innovation from the ancient world to the development of mass market publishing, which I count as the invention of the rotary press, was 807 years. By comparison time to innovation in the twentieth century took approximately 11 years on average. If we look at publishing in the internet age we would see an even faster rate of change—in some cases with only months between new innovations. What are you doing to keep up?
