To understand the importance of the Internet to commerce you need only look at this Webpage of numbers. Here is a sample:* There were 20 trillion emails sent last year, excluding spam
* There are a quarter of a billion websites
* Nearly 40% of all adult humans on the planet are now using the Internet. (6.8x.66x 1.8)

Commerce probably can't avoid looking those numbers square in the face.
