Like most other social phenomena, the distribution of internet traffic has converged into a power law distribution. The author hints at it, but doesn't really underline the key driver of this change: serving vast amounts of flash and video content. Not only do flash and video take up much more traffic than html+css, but the backend infrastructure necessary to serve large amounts of flash and video is something that only a very few well-capitalized companies can do on a large scale. So larger files/streams + fewer capable companies = heavily skewed distribution of traffic.
