Channel expansion theory

rdf:langString Channel expansion theory

rdf:langString Channel expansion theory (CET) states that individual experience serves as an important role in determining the level of richness perception and development towards certain media tools. It is a theory of communication media perception that incorporates experiential factors to explain and predict user perceptions of a given media channel. The theory suggests that the more knowledge and experience users gain from using a channel, the richer they perceive the medium to be. The more experience, the more stable the knowledge base the person builds, the more knowledge he gains from the given media channel, thus the richer communication he would have using that channel, and ultimately the richer he would perceive the channel. There are four experiential factors that shapes individual's perceived media richness: experience with the channel, experience with the message topic, experience with the organizational context, and experience with a communication partner. Channel expansion theory was developed by John. R. Carlson and Robert W. Zmud in 1999.
