Core77 Articles: Pixelvision is an article on the history of the pixel. I got the link from Matt K’s blog.
Matt points out that this sort of cultural history is healthier than another book on electronic writing. He is right, though we will probably get tired of such “the world in a blade of grass” stories when there are too many of them. It is a recent trend with books like Longitude and the book on the pencil as good examples.
