Types of rich content you can present include PowerPoint slides delivered in real-time, annotation tools, live software demonstrations, polling, whiteboards, web tours and streaming audio and video. As a presenter, you're given full control of the meeting. In smaller collaborative meetings oriented towards workgroups who need to closely collaborate over a document or idea, even more interactivity is possible, such as creating new content on the fly and illustrating points collaboratively on whiteboards. The benefits of Web conferencing are clear. Web conferences can either serve as a valuable visual supplement to an audio conference call, or can in certain circumstances replace the need for travel to an in-person meeting or presentation.
Audio conference calls today frequently include a visual complement.
Slides or meeting documents are often faxed or emailed prior to the event and are a subject of discussion during the meeting. This approach has its practical limitations, however, since documents are often lost or misplaced in transit, or not available to everyone. It is also challenging to keep everyone in sync with a presentation, as some may skip ahead, some may fall behind, and some slides may require thoughtful explanation and illustration, which can prove to be very difficult. Web conferencing enables a presenter to completely control the delivery of the presentation, and control what gets seen when.
