The article focuses on electronic ink. The company Gyricon calls it Smart Paper and E Ink Corp. calls it electronic ink. Both companies have developed and are marketing a new type of electronic paper that could vastly change communications and visual media technology. As a display technology, ink on paper has many advantages. Gyricon and E Ink are betting that paper coated with electronic ink can enhance the value and pleasure traditionally associated with reading a printed, bound book.
