Thesis
Each leap and evolution in technologies and the socialization of them creates expectations of a standard. One example is “land line” telephony. The dial tone is the first noise you hear when you lift the phone from the cradle, if the line is working. If you do not hear the dial tone, you know something is wrong, but you expect to hear a dial tone and generally do not notice it otherwise. Other examples of technologies we expect to just “be there” include television, radio and, more currently, connectivity, both wireless and cell.
