Most likely the first form of communication among humans was that of the signs and signals used in prehistory, one which reflected in material culture are different manifestations of prehistoric art. The appearance of writing is taken as a milestone in history began. From that moment, the economic and social changes were driving the birth and development of various media, from those related to writing and mechanization (print-fifteenth century-) to the media linked to the age of electricity (first half of the twentieth century) and the revolution in information and telecommunications (scientific-technical revolution or third industrial revolution, since the second half of the twentieth century-), each of which are essential for the different phases of the so-called process of globalization . --- Important Dates XIV century: the invention of printing (possibly by Johannes Gutenberg in 1). ---- Purposes The main purpose of the media is precisely communicate, but according to his kind of ideology can specialize in, inform, educate, transmit, entertain, form opinions, to teach, control, and so on. Positive. The positive features of the media are that they allow large information content extended reach places on the planet immediately. The media, likewise, enable many personal relationships remain united, or at least not completely disappear. Another positive factor is given in the economic field: who owns the use of the media can generate a certain kind of consciousness on a kind of product, ie, can generate its own demand, since the media often play the role of trainers opinion. Then, seen from the business, is a largely positive aspect by allowing the marketing and advertising for the world. Negative. The negative features fall in handling information and using it for self-interest of a specific group. In many cases, tend to form stereotypes, followed by many people, using the scope that takes the message to its diffusion (as individuals or groups to generalize). Due to the complexity of the media, Harry Pross (1972) has separated these into three categories based on their technical level. In 1997 Manfred Fassler contributed a new category and are thus classified as follows: Primary means (own resources) are linked to the human body. They do not need the use of any technique for communication, which in turn is synchronous. Examples: Narrator, Cura, Theatre. ---- Cartoon The cartoon, which became the mass media through the evolution of the press nineteenth-century golden age in the number of readers after the Second World War. With the proliferation of new forms of leisure in the second half of the twentieth century away from being a mass medium in most countries, creating more expensive formats, such as albums or magazines luxury and looking for new types of readers. The phone is a device designed to transmit electrical signals through the conversation two people at once.

Moreover, according to the mentioned authors, listeners tend to turn the radio on a regular and predictable schedules. The most popular times are the "hours of driving," when you are on your vehicle are a vast captive audience. Its main advantages are: Good local acceptance; high geographic and demographic selectivity;.

It is an audiovisual medium that allows mass to reach a wide group of people "captive" but a low selectividad.Sus advantages are a captive audience and sharper color ads.

Internet is a method of networking computers deployed in a set of protocols called TCP / IP and ensures that heterogeneous physical networks function as a network (logical) one. It makes its first appearance in 1969, when ARPAnet makes its initial connection between three universities in California and one in Utah.

One of the criticisms of the mainstream media is their subordination to powerful business groups. In some countries, economic groups are owners of large media, such as Grupo Clarín in Argentina, Televisa in Mexico, national television (TVN) in Panama and Grupo Prisa (Spain). Thus, according to economic, political and social, multimedia is used to achieve objectives that transcend the communication objective. As a way to counter this subordination to private interests, information networks have emerged calling themselves "independent" non-profit groups and volunteer-based. Among the best known is Indymedia. -> Created for Jeanne Siegel |
