Media of Transmission

Information products cannot be bought or sold alone. While it is the arrangement of symbols that gives utility, the symbols have to be recorded or expressed in some material form. In the examples above, we have symbols recorded on paper blueprints and plans, on paper in a bound book, expressed in oral speech, in computer code on a hard disk, and on compact disks. Each of these is a "medium" for the preservation and transmission of the symbols, and the plural of "medium" is "media." Information products cannot be bought, sold, given away or even preserved except in conjunction with some medium.
