� The current percent of total network traffic that is video has doubled from two years ago and expected to double again one year from now.

� Video conferencing, digital security cameras, and desktop streaming video are the most common video technologies used on a company-wide basis today. Companies are likely to say they will spend more on video conferencing, telepresence, and digital security cameras next year.
