Abstract:

Advancing technology allows us to use the new technologies of podcasts (audio recordings delivered as .mp3 files) and vidcasts, or more properly, broadcast video to convey technical information. Effective audience analysis will determine whether multimedia is right for our users. We use the same correct rhetorical principles to communicate information aurally and visually as we do when creating text.
