The selection and use of communication media has been the center of attention for a great number of researchers in the area of organizational communication. The channel expansion theory combines elements of the main theories in this area; however, these investigations have a static cross-sectional design rather than a longitudinal analysis. With the objective of filling this gap, we research how the perception of media richness varies over time with a longitudinal study. The results suggest that the perception of richness of a channel by different individuals is different but that those variations due to a change in acquired experiences, are influenced in a similar and significant way by all individuals over time.
