 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.
