Social media has been broadly defined to refer to 'the many relatively inexpensive and widely accessible electronic tools that enable anyone to
publish and access information, collaborate on a common effort, or build relationships.
There are many effects that stem from Internet usage. According to Nielsen, Internet users continue to spend more time with social media sites than any other type of site. At the same time, the total time spent on social media in the U.S. across PC and mobile devices increased by 99 percent to 121 billion minutes in July 2012 compared to 66 billion minutes in July 2011. For content contributors, the benefits of participating in social media have gone beyond simply social sharing to building reputation and bringing in career opportunities and monetary income, as discussed in Tang, Gu, and Whinston (2012)
