In cable television, many governments, including the ones of the United Kingdom, the United States, and Canada, apply a must-carry regulation stating that forces a cable TV provider to carry the public interest programming, like locally licensed television stations, on a provider's system. In some countries, this "traditional" approach had been extended to the Internet information sources. Similar approach in other sectors, like telecommunications, is called universal service.
