The media are divided, by their physical structure, into:
In general terms, audiovisual media are those that can be heard and seen. That is, devices that rely on images and sounds to transmit information, such as television and movies.
From its appearance in the 30’s to the beginning of the 21st century, television has been the medium with the highest ratings of audiences or audiences worldwide. This is due to its characteristics as an informative tool: its immediacy in the coverage of events, the resources it uses (images, sound, presenters, recording sets) and, above all, the possibility it offers to see the facts -and its protagonists-in real time and miles away.
Even today, with the arrival of new media, television maintains its level of influence over most sectors of society, because its devices are cheap and easily accessible.
At a formal level, television proposes the use of a wide variety of formats when transmitting information. They include news, soap operas, documentaries, reports, and interviews, cultural, pedagogical and scientific programs, among others. Thanks to the accelerated technological development of the last decades of the twentieth century and the first of the 21st century, each format combines images, texts and sounds, and also raises constant contact and interaction with the audience. For all these reasons, television is currently a means of communication that, it is considered, raises a reflection on the democratic character of our societies.
The cinema has not been considered as a means of informative communication, despite having been used in this way on several occasions. It is true that its audiovisual characteristics allow it to function as a powerful message transmission platform, but the dimensions of its production and the interests of its producers have made it, until today, considered as a cultural entertainment, dedicated to the creation of stories, fiction and documentaries, of high impact and with emotional or historical significance.
However, from its appearance, at the end of the 19th century, the cinema functioned as a transmitter of informative messages. For example, in the 30s and 40s, in Nazi Germany and Fascist Italy, cinema was used as a means of propaganda: the rulers of both countries understood it as a fundamental platform to transmit to their peoples the scope of their governments. ultra-right. This generates a reflection on the possibilities of the mass media to generate imaginaries and to influence the decisions of our societies.
Radio is the only medium that is part of the media that transmit information through sound formats. Its importance lies in the fact that it is the medium that obtains information more easily and has a much simpler production process than that of television. In addition to the few requirements involved in its production, the radio does not need images to communicate, nor a large team of workers; radio journalists need only be in the scene, in addition to having a microphone and a sound booth with which the emission of the information on the air is achieved.
