Webinar is a new conference mode that uses streaming media technology to integrate slide presentations, audio or video files, shared desktops, etc. It provides a three-dimensional representation of the information that companies are seeking to promote, ensuring the richness and comprehensiveness of presentations. The Webinar takes full advantage of the convenience and interactivity of the web, no longer limited by time and space, but more effective in time, wide in scope, high in coverage, and low in cost of user participation.
