Social media marketing  has impacted the way organizations communicate. With the emergence of Web 2.0, the internet provides a set of tools that allow people to build social and business connections, share information and collaborate on projects online.

Social media marketing programs usually center on efforts to create content that attracts attention and encourages readers to share it with their social networks. A corporate message spreads from user to user and presumably resonates because it appears to come from a trusted, third-party source, as opposed to the brand or company itself. Hence, this form of marketing is driven by word-of-mouth, meaning it results in earned media rather than paid media.

Social media has become a platform that is easily accessible to anyone with internet access. Increased communication for organizations fosters brand awareness and often, improved customer service. Additionally, social media serves as a relatively inexpensive platform for organizations to implement marketing campaigns. With emergence of channels like Twitter and Facebook, the barrier to entry in social media is greatly reduced.
