Any medium presents a figure whose ground is always hidden, or subliminal. In the case of TV, as of the telephone and radio, the subliminal ground could be called the discarnate or disembodied user. This is to say that when you are “on the telephone,” or “on the air,” you do not have a physical body. In these media, the sender is sent, and is instantaneously present everywhere. The disembodied user extends to all those who are recipients of electric information. It is these people who constitute the mass audience, because mass is a factor of speed rather than quantity, although popular speech permits the term mass to be used with large publics.
