Internet traffic update: right on the nose

As nearly every indicator of economic growth plummets, the Net maintains its rise. Given my research on the growth of the Internet, I’m always interested in the latest data. Here are year-end estimates, courtesy of Andrew Odlyzko at the University of Minnesota.

Monthly U.S. traffic by year-end 2008 was about 1.5 exabytes (10^18) per month, for an annual growth rate of around 50-60%. (An exabyte is a million terabytes, or a billion gigabytes.) My research suggests the Net should continue to grow at an annual compound rate of around 56% through 2015.
