It is often referred to as synonymous with mass media or news media, but may refer to a single medium used to communicate any data for any purpose.

Mass media is the term used to denote, as a class, that section of the media specifically conceived and designed to reach a very large audience. It was coined in the 1920s with the advent of nationwide radio networks and of mass-circulation newspapers and magazines. The mass-media audience has been viewed by some commentators as forming a mass society with special characteristics, notably atomization or lack of social connections, which render it especially susceptible to the influence of modern mass-media techniques such as advertising and propaganda.
During the 20th century, the advent of mass media was driven by technology that allowed the massive duplication of material at a low cost. Physical duplication technologies such as printing, record pressing and film duplication allowed the duplication of books, newspapers and movies at low prices to huge audiences. Television and radio allowed the electronic duplication of content for the first time.
Mass media had the economics of linear replication: a single work could make money proportional to the number of copies sold, and as volumes went up, units costs went down, increasing profit margins further. Vast fortunes were to be made in mass media.
