For many businesses, including investment banking, accounting, law, technology services, and management consulting, extensive travel is a fact of life. The expenses incurred by business travel have been steadily rising in recent years, primarily due to increasing energy costs. In an effort to reduce travel expenses, many companies, both large and small, are using videoconferencing and Web conferencing technologies.
A June 2008 report issued by the Global e-Sustainability Initiative and the Climate Group estimated that up to 20 percent of business travel could be replaced by virtual meeting technology.
A videoconference allows individuals at two or more locations to communicate through two- way video and audio transmissions at the same time. The critical feature of videoconferencing is the digital compression of audio and video streams by a device called a codec. Those streams are then divided into packets and transmitted over a network or the Internet. The technology has been plagued by poor audio and video performance in the past, usually related to the speed at which the streams were transmitted, and its cost was prohibitively high for all but the largest and most powerful corporations. Most companies deemed videoconferencing as a poor substitute for face-to-face meetings. However, vast improvements in videoconferencing and associated technologies have renewed interest in this way of working. Videoconferencing is now growing at an annual rate of 30 percent.
Proponents of the technology claim that it does more than simply reduce costs. It allows for 'better' meetings as well: it's easier to meet with partners, suppliers, subsidiaries, and colleagues from within the office or around the world on a more frequent basis, which in most cases simply cannot be reason- ably accomplished through travel.
