“Our personal and social consequences of any medium – that is, of any extension of ourselves – result from the new scale that is introduced into our affairs by each extension of ourselves, or by any new technology” – Marshall McLuhan. Understanding Media (1964), P1.
Anyone can post anything daily. No matter who you are in the world, your voice can be heard and shared. In simple terms, there is no filtering on the internet (though it is more complicated than this), and your voice can influence many (many to many). You can post something on Youtube that will ultimately be taken down for its content. However, it has already reached an audience on such a large scale and distributed across platforms, and so its impact has already happened, despite it possibly being taken down in 10 minutes. You can broadcast to the entire network, and then it can be distributed through multiple channels by the audiences participating. These are the personal and social consequences of the media.
