Social media are online platforms that allow users to share content, information and communicate with other users. Some of the earliest social media sites included Six Degrees and blogging sites in the late 1990s. Today, social media has become an important tool for communication, news, and decision making. Popular social media sites include Facebook, Twitter, Instagram, YouTube and WhatsApp. While social media provides advantages like large audiences and brand building, it also poses disadvantages such as decreased face-to-face skills and privacy issues.
