The widespread provision of public utilities as public services in developed countries usually began in the late nineteenth century, often with the municipal development of gas and water services. Later, governments began to provide other services such as electricity and healthcare. In most developed countries, local or national governments continue to provide such services, the biggest exceptions being the U.S. and the UK, where private provision is arguably proportionally more significant. Nonetheless, such privately provided public services are often strongly regulated, for example (in the US) by Public Utility Commissions.
