Telecommunications in Russia
Russia was among the first countries to introduce radio and television. Due to the enormous size of the country Russia leads in the number of TV broadcast stations and repeaters. There were few channels in the Soviet time, but in the past two decades many new state-run and private-owned radio stations and TV channels appeared.The telecommunications system in Russia has undergone significant changes since the 1980s, resulting in more than 1,000 companies licensed to offer communication services today. The foundation for liberalization of broadcasting was laid by the decree signed by the President of the USSR in 1990. Telecommunication is mainly regulated through the Federal Law ""On Communications"" and the Federal Law ""On Mass Media""The Soviet-time ""Ministry of communications of the RSFSR"" was through 1990s transformed to ""Ministry for communications and informatization"" and in 2004 it was renamed to ""Ministry of information technologies and communications (Mininformsvyazi)"", and since 2008 Ministry of Communications and Mass Media.Russia is served by an extensive system of automatic telephone exchanges connected by modern networks of fiber-optic cable, coaxial cable, microwave radio relay, and a domestic satellite system; cellular telephone service is widely available, expanding rapidly, and includes roaming service to foreign countries. Fiber to the x infrastructure has been expanded rapidly in recent years, principally by regional players including Southern Telecom Company, SibirTelecom, ER Telecom and Golden Telecom. Collectively, these players are having a significant impact of fiber broadband in regional areas, and are enabling operators to take advantage of consumer demand for faster access and bundled services.
