You Media they represent the vehicles or instruments used to spread information among men. Examples are: radio, television, telephone, newspaper, magazine, internet, cinema, among others.
From the development of science and new technologies, the means of communication have significantly advanced, providing the dissemination of knowledge and communication in the world.

Communication
According to "Communication theory", the sender (or announcer) is the one who sends the message. The receiver (or interlocutor) is the one who receives and decodes it.
The "communication channel" designates the place, or means by which the message will be sent to the receiver.
Thus, the means of communication approach the “channel”, insofar as they represent the vehicle between the sender and the receiver. Language can be written, sound, audiovisual, such as newspapers, magazines (written communication), radio and television (audiovisual communication), etc.
history of the media
The history and origin of the media arise from the human need to express themselves. In prehistory, rock art (primitive drawings inside caves or grottos) already points out this importance in the lives of men.
Since the emergence of writing and the alphabet, man has been developing ways to expand knowledge and create a human “culture”.
This is exactly what makes us different from animals, that is, the creation of a culture, generated by human communication. Animal species do not have a "language" that allows them to create cultures, beliefs and traditions that will be passed on from generation to generation.
It took centuries of development until we reached the point of communication that we have reached, that is, in the era of information technologies and mass culture. These means represent, to a large extent, factors in the development of human society, since it has disseminated (and continues to disseminate) knowledge around the world, in different times and spaces.
After writing, supports such as papyrus, parchments and, later, books appeared, spread from the creation of the press in the 14th century.
O mail is considered one of the oldest means of communication, and the Egyptians already used it to send documents and letters. In the past, birds such as doves and crows were used to send messages.
With the development of studies on electricity, already in the 18th century, the Telegraph, instrument connected by wires and electromagnets. Based on the emission of electromagnetic impulses, it sent messages over long distances.
This instrument was considered one of the great revolutions of the means of communication, being one of the first modern communication systems.
Telegraphs were essentially used by governments, where the message (written or visual) was transmitted by codes. In this context, the Morse Code appears, invented by the American painter Samuel Morse (1791-1872).
In the 20th century, radio and telephone were the main means of communication.
Through electromagnetic waves, radio was created and used to spread information, as well as to serve as entertainment, with music and radio soap operas. It was an important communication tool used during periods of war.
already the telephone, represented the evolution of the telegraph. This wired instrument sends voice messages over long distances in real time, while telegraphs only send pictures or text messages.
Unlike the telegraph, the telephone has expanded and is now widely used: public, analog, digital, wireless and cell phones.
In the 20th and 21st centuries, television and the internet were (and continue to be) the main means of communication.
Television is a simultaneous sound and image reproduction instrument that works by means of electromagnetic waves. already the Internet, represents a global system of computer networks that uses the most varied network technologies: electronic, wireless and optical.
Researches show that television is still the most used means of communication by man and, in second place is the internet, which is increasingly expanding around the world in the field of communications instant messages.
Types of media
According to the field and performance, there are two types of media:
- Individual: the individual means of communication are based on internal, interpersonal (between people) communication, for example, the letter (mail), telephone, fax.
- Pasta: the mass media are broader and more external. They are intended to communicate with a large number of people, for example, newspapers, magazines, internet, television, radio.

- Audiovisuals: fusion of sound and image, for example, television and cinema.
