C2C Definition
C2C stands for consumer to consumer electronic commerce. The Internet has facilitated new types of C2C although it is important to note that this kind of commerce -- in the form of barter, yard sales, flea markets, swap meets, and the like -- has existed since time immemorial. Notably, most of the highly successful C2C examples using the Internet actually use some type of corporate intermediary and are thus not strictly "pure play" examples of C2C. An example of consumer-to-consumer electronic commerce would be Ebay.
