Social Commerce or Social E-commerce is an amalgamation of e-commerce and social media where an interactive atmosphere between buyers and sellers, through user contribution, assists in the sale or purchase of a product. To put it bluntly, social e-commerce is the adoption of social media for e-commerce.
The term social commerce was coined by Yahoo! in November 2005 to describe a synergic set of lists compiled by users to rate a product purchased by them.
