Today, 2,000 years after the Chinese invented it, paper has become smooth, light-weight, and flexible. Furthermore, it can be produced inexpensively and in mass quantity. It is highly portable, and the ready availability of it has spurred the development of printing, thus making reading an activity for the common man.
