Now we think about media in different ways. One of the ideas is that media is a social institution that connects and disconnects people in different ways. For instance, what we call "broadcasting media" enables the relationships between audience and producers. Or, on the other hand, media can connect people without these distinctions, making them peers.
Contrary to this, the broad understanding of media is close to the technology. We can think about almost anything as a media: a book, traffic lights, a cup of coffee, your body and clothes. Everything that has a message is a media (an innuendo to Marshall McLuhan).
