Ecommerce (e-commerce) or electronic commerce, a subset of ebusiness, is the purchasing, selling, and exchanging of goods and services over computer networks (such as the Internet) through which transactions or terms of sale are performed electronically. Contrary to popular belief, ecommerce is not just on the Web. In fact, ecommerce was alive and well in business to business transactions before the Web back in the 70s via EDI (Electronic Data Interchange) through VANs (Value-Added Networks).
Ecommerce can be broken into four main categories: B2B, B2C, C2B, and C2C.
- B2B (Business-to-Business)
- B2C (Business-to-Consumer)
- C2B (Consumer-to-Business)
- C2C (Consumer-to-Consumer)
