The history of communicating with many at once
Traditional
media can be limiting when viewed as the only influence on new social
media. Think of a famous athlete's Facebook post seen and raucously
responded to by thousands of people. Would that have been possible
through traditional media like a paper newspaper or radio broadcast? No.
But now imagine it in this ancient amphitheater in Syria (below). That
athlete could have shouted an insult at an opponent, and gotten roars of
approval and disapproval from the crowd. Spectators may even have
gotten into fights with one another. Those types of interactions have a
long social history.

The
Bosra pano in Syria: This amphitheater from the ancient Roman empire
afforded viewership by a large crowd that also interacted with one
another.
Humans can communicate to broad and distant audiences using many other means outside of print or broadcast media. These include:
- Vocalization and voice amplification
- Staging for visibility
- Oversize objects
- Movement and dance repertoires
- Songs and repetition

This
giant puppet is one example of a means developed before digital social
media to communicate a message to many people using performance and
imagery.
Some
of these means of communication are very old. But the smartest
developers and users of new media let every possible means of
communication and visibility inspire their designs and practices.
It
is important to recognize that when we use media, we communicate and
spread our ways of interacting with these media, not just the content
delivered by the media. Theorist Marshall McLuhan referred to this with
the phrase, "The medium is the message".
When
developers consider new features, they have to consider what is present
in the cultures that will interact with those media. If a feature
relies upon brand new methods of interaction, it increases the
likelihood that those media will confuse users. See one interesting way
people are looking at new gestures developed in the digital age.
