Social Media overview
Social media refers to online tools and services that allow any Internet user to create, publish and share content. The “social” in social media results from individual users connecting with one another through these channels and forming online communities where they share information and knowledge and offer one another support and networking opportunities. Social media facilitates the sharing of content, thus expanding the reach of your core message and enabling others to pass it along to their friends and networks. Popular social media sites include, but are not limited to, Facebook, Twitter, YouTube, blogs, LinkedIn, Flickr, Foursquare and iTunes U.
