Modern electronic commerce typically uses the World Wide Web at least some point in the transaction's lifecycle, although it can encompass a wide range of technologies such as e-mail as well. A small percentage of electronic commerce is conducted entirely electronically for "virtual" items such as access to premium content on a website, but most electronic commerce eventually involves physical items and their transportation in at least some way.
