Although the topic is highly debated, many agree that Facebook is one of the most prominent modern examples of a social utility. Facebook has even described itself as "a social utility that connects people with friends and others who work, study, and live around them."
Despite the disparity, the social media giant fits many of the aspects that define social utilities. The concept is based on a philosophy, utilitarianism, which addresses how members of a society ought to act to promote the common welfare of society. In a modern sense, social utilities may resemble public utilities, which serve large populations of people. Facebook's primary function is to connect people through a virtual community. The nature of the debate regarding Facebook is whether or not society benefits from its use.
