As noted above, a social networking service is an online platform. It allows individuals to create profiles, share content, and interact with others. Social networking services may also be referred to as social networks. Some of the most commonly used SNSs include Facebook and X (formerly Twitter).
Social networking services work by providing a forum for people to develop connections with others. Individuals can find and connect with people they already know, such as family and friends, or interact with strangers who may share similar interests with them.
The SNS business model is typically based on online advertising, often through targeted ads that make use of an individual’s personal information, search habits, location, or other kinds of data. Alternatively, or in addition, the platform may sell users’ personal information to third parties. Ubiquitous mobile technologies, such as smartphones and tablets, have sped the adoption of SNS platforms worldwide.
