Types

Mediated groups take several forms:

• Teleconferences in which the group members talk via the telephone.
• Videoconferences in which a video and audio connection allows the group members to communicate with each other.
• Computer-mediated discussions such as Listservs, chat, or Usenet, in which the group members communicate via email.

Advantages

There are several advantages to mediated groups. First, they are usually inexpensive to operate. Instead of traveling long distances to meet, groups can meet over the telephone or via email. In addition, when using email or telephones, the group does not have to meet as a whole. It can carry on its business over time and without everyone being present.

Disadvantages

There are also some disadvantages to mediated groups. When communicating via the telephone or by email, it is difficult to judge other group members' nonverbal expressions. Also, the technology can be a difficult adjustment. Finally, the social aspects of the group are downplayed when the group does not meet face to face.
