Television in Bulgaria was introduced in 1959. Although the Bulgarian media market is small, it is one of the most vibrant and highly competitive in Central and Eastern Europe. Global players such as News Corporation, Modern Times Group, Central European Media Enterprises HD Sofia TV and Fox Broadcasting Company and others operate the biggest and most popular media outlets in the country.
In 1954, a team at the Machine and Electrotechnics Institute in Sofia (today called the Technical University of Sofia) started experimental television broadcasting with two antennas (one for sound and one for image) on the roof of a building near the Vasil Levski monument in the city, after having previously conducted successful cable test transmissions. These experimental broadcasts aroused the interest of the Ministry of Communications, which decided to build a broadcasting tower in Sofia, with a state-controlled channel to air from it. The new channel started with an unofficial broadcast on November 1, 1959, and made its first official broadcast several days later with the live coverage of the November 7 , commemorating the Russian Revolution of 1917. The experimental channel of the MEI did not air anything but a test chart on that day, although it did show a greeting to the new Sofia Television Station three times after 19:05. The MEI channel continued to operate until late 1960, when the team started working on the future introduction of color television.
The new channel, later referred to as "Bulgarian Television" (BT) used the OIRT standard of 625 lines and 25 frames per second. It also used the D/K audio system, which was generally done to prevent reception of Western European stations in Eastern Bloc countries. Public attention was quickly caught by the new medium, and the number of bought and registered television sets increased gradually. In 1960, a powerful 20 kilowatt transmitter was installed at Botev Peak, covering a large area of the country. Later, more transmitters and retranslators were placed in various cities, towns and villages around the country.
