Desktop videoconferencing (DVC) represents a convergence of video, audio, and real-time collaboration support software into a familiar personal computer. A longitudinal field quasi-experiment evaluated the efficacy of desktop videoconferencing systems to amplify informational influence relative to baseline face-to-face treatment. The DVC systems were used in both real geography distributed teams and local nonproximate teams. The result indicate indicate that the DVC systems did not provide greater informational influences than face-to-face environments. Interpretation of these results and issues of media convergence are discussed in relation to future media research. Interpretive subject comments and observations from the study are also included.
