Social networking is the use of Internet-based social media sites to stay connected with friends, family, colleagues, customers, or clients. Social networking can have a social purpose, a business purpose, or both, through sites such as Facebook, Twitter, LinkedIn, and Instagram, among others. Social networking has become a significant base for marketers seeking to engage customers.
Despite some stiff competition, Facebook remains the largest and most popular social network, with over two billion people using the platform. It was followed, in order of popularity, by Instagram, Facebook Messenger, Twitter, and Pinterest.
