A public service or service of general (economic) interest is any service intended to address the needs of aggregate members of a community, whether provided directly by a public sector agency, via public financing available to private businesses or voluntary organisations, or by private businesses subject to government regulation. Some public services are provided on behalf of a government's residents or in the interest of its citizens. The term is associated with a social consensus (usually expressed through democratic elections) that certain services should be available to all, regardless of income, physical ability or mental acuity. Examples of such services include the fire services, police, air force, paramedics and public service broadcasting. Even where public services are neither publicly provided nor publicly financed, they are usually subject to regulation beyond that applying to most economic sectors for social and political reasons. Public policy, when made in the public's interest and with its motivations, is a type of public service. Source: Wikipedia (en)
