Evolution of ComTech: Rogers' Diffusion of Innovations

If we can learn anything from the history of communications technology, it is that there will always be new innovations that will take off, only to be replaced or outdone by another.  The expression 'TV killed the radio' is applicable to almost all communications technology.  One example other than TV and radio is the original emergence of motion pictures in 1895.  Because of the accessibility of motion pictures, the use of print media and theater was extremely diminished despite being so popular for several centuries.
