Social commerce is a subset of electronic commerce that involves social media, online media that supports social interaction, and user contributions to assist online buying and selling of products and services.More succinctly, social commerce is the use of social network(s) in the context of e-commerce transactions.The term social commerce was introduced by Yahoo! in November 2005 which describes a set of online collaborative shopping tools such as shared pick lists, user ratings and other user-generated content-sharing of online product information and advice.The concept of social commerce was developed by David Beisel to denote user-generated advertorial content on e-commerce sites, and by Steve Rubel to include collaborative e-commerce tools that enable shoppers "to get advice from trusted individuals, find goods and services and then purchase them".
