Mass communication is the term used to describe the academic study of the various means by which individuals and entities relay information through mass media to large segments of the population at the same time. It is usually understood to relate to newspaper and magazine publishing, radio, television and film, as these are used both for disseminating news and for advertising. Mass media denotes a section of the media specifically designed to reach a very large audience such as the population of a nation state. The term was coined in the 1920s with the advent of nationwide radio networks, mass-circulation newspapers and magazines. However, some forms of mass media such as books and manuscripts had already been in use centuries. The public media has a similar meaning: it is the sum of the public mass distributors of news and entertainment across media such as newspapers, television, radio, broadcasting, which may require union membership in some large markets such as Newspaper Guild, AFTRA, & publishers. Mass media includes Internet media like blogs, message boards, pod casts, and video sharing because individuals now have a means to exposure that is compatible to that of a previously restricted select group of mass media producers. The communications 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. The term "MSM" or "mainstream media" has been widely used in the blogosphere in discussion of the mass media and media bias. 'Mass communication' can be seen as institutionalized production and generalized diffusion of symbolic goods via the fixation and transmission of information or symbolic content. It is known that systems of information have shifted from analog to digital. This has indeed advanced the communication between individuals. With the existence of Infrared, Bluetooth and Wi-Fi, cell phones are no longer solely a tool for audio transmission. We can transfer photos, music documents or even games and email at any time and anywhere. The development of media technology has indeed advanced the transmission rate and stability of information exchange.
