Mass media refers collectively to all media technologies—including television, newspapers, and radio—which are used for mass communications (delivering messages to a large audience), and to the organizations which control these technologies.
Mass media play a significant role in shaping public perceptions on a variety of important issues, both through the information that is dispensed through them, and through the interpretations they place upon this information. The also play a large role in shaping modern culture, by selecting and portraying a particular set of beliefs, values, and traditions (an entire way of life), as reality. That is, by portraying a certain interpretation of reality, they shape reality to be more in line with that interpretation.
History
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 first high-circulation newspapers arose in the eastern United States in the early 1800s, and were made possible by the invention of high-speed rotary steam printing presses. The increase in circulation, however, led to a decline in feedback and interactivity from the readership, making newspapers a more one-way medium.
The telegraph separated communications from transportation, enabling messages to be transmitted instantaneously over large distances.
