The invention of the printing press in the late 15th century gave rise to some of the first forms of mass communication, by enabling the publication of books and newspapers on a scale much larger than was previously possible. The invention also transformed the way the world received printed materials, although books remained too expensive really to be called a mass-medium for at least a century after that.

During World War II, the U.S. government encouraged the implementation of technology of instruction for military training programs.
This gave impetus to a system approach to instruction to include: micro-teaching, individualized instruction, Language laboratories, behavioral laboratories, behavioral objectives, computer assisted instruction and among others
