B2C- BUSINESS TO CONSUMER

Definition:

Business that sells products or provides services to end-user consumers.

Information:
While business-to-consumer activity exists both online and offline, the acronym B2C has primarily been used to describe the online variety.
B2C businesses played a large role in the rapid development of the commercial Internet in the late 20th century. Large sums of venture capital flowed to consumers in the form of free online services and discounted shopping, spurring adoption of the new medium.
When the capital markets turned sour, however, the B2C companies were among the first to fall, and they fell fast. Many companies tried to follow the herd of investors by undergoing a B2C to B2B makeover.

The term B2C, once popular, is now less frequently used, and the infrequent references are often followed by "...is dead." However, some analysts still predict that consumer businesses will thrive online, just not as big and fast as initially predicted. This is not news, of course, to the many niche businesses that are already enjoying success online.

B2B- BUSINESS TO BUSINESS

Business-to-business (B2B) describes commerce transactions between businesses, such as between a manufacturer and a wholesaler, or between a wholesaler and a retailer. Contrasting terms are business-to-consumer (B2C) and business-to-government (B2G).

The volume of B2B transactions is much higher than the volume of B2C transactions. The primary reason for this is that in a typical supply chain there will be many B2B transactions involving subcomponent or raw materials, and only one B2C transaction, specifically sale of the finished product to the end customer. For example, an automobile manufacturer makes several B2B transactions such as buying tires, glass for windshields, and rubber hoses for its vehicles. The final transaction, a finished vehicle sold to the consumer, is a single (B2C) transaction.
The term "business-to-business" was originally coined to describe the electronic communications between businesses or enterprises in order to distinguish it from the communications between businesses and consumers (B2C). It eventually came to be used in marketing as well, initially describing only industrial or capital goods marketing. Today it is widely used to describe all products and services used by enterprises. Many professional institutions and the trade publications focus much more on B2C than B2B. This is a strange development as most sales and marketing people work in B2B.

C2C- CONSUMER TO CONSUMER

Consumer-to-consumer (C2C) (or citizen-to-citizen) electronic commerce involves the electronically-facilitated transactions between consumers through some third party. A common example is the online auction, in which a consumer posts an item for sale and other consumers bid to purchase it; the third party generally charges a flat fee or commission. The sites are only intermediaries, just there to match consumers. They do not have to check quality of the products being offered.

Universities:
C2C are becoming more popular amongst students in universities because these are large communities in the same geographical region that are low on money. So they are looking for deals very often and these kinds of websites offer this. Universities themselves set up places for students to sell textbooks and other stuff to other students, you can even advertise that you are subletting your apartment. An example of this from above is Tiger books and Dalhousie University Classifieds, both of these are put together by the school itself for the students.
