While social presence has evolved / through many iterations / since its first development / within the context of the landline telephone, / the perception or feeling of being connected / with the other person / within the context of the conversation / has persisted.

Some research has explored / specific technologies / and the extent to which their characteristics / lead to a feeling of social presence.

For example, / some researchers have studied / the "richness" of the media, / or the number of cues available / to convey social presence.

A telephone call, / which provides for audio cues / and immediate feedback, / is potentially richer / than an email, / which provides only textual cues / and no immediate feedback.

Videoconferencing would be considered / richer than the phone / because of the addition of visual cues, / making it closer to replicating / a perceived gold standard / of face-to-face, in-person social presence.

Researchers have suggested / that successful managers would choose / rich media / for confusing or ambiguous messages / and lean or less rich media / for messages that were more routine in nature.

For example, / if you wanted to discuss / a complicated client agreement, / it would be best to choose / a face-to-face meeting.

In contrast, / if you were going to inform your team / about a change in meeting time / from 3 to 3:30, / you might send out / a generic email to everyone.

These different channels of communication / were considered by researchers / as a type of container / that the message comes in.

To be a good communicator, / you need to choose / the right container.
