This document discusses the advancement of technology over the last 50 years through various communication theories. It analyzes how computers have changed from the 1970s Apple 2 to modern devices through media system dependency theory. Uses and gratification theory is applied to explain how television usage has evolved to meet different personal needs. Social learning theory demonstrates how people learn from and imitate behaviors seen on television. Critical mass theory explains the development of telephones from individual radios to today's cellular networks as communication technologies that benefit individuals communicating with one another. The conclusion states that technology will continue advancing as individuals incorporate communication theories into their daily lives seeking improved options.
