Mediaset S.p.A., known as Gruppo Mediaset in Italian, is an Italian-based mass media company which is the largest commercial broadcaster in the country. Founded in the 1970s by former Italian prime minister Silvio Berlusconi and still controlled today with a 38.6% stake by his family holding company Fininvest, the group competes primarily against the public broadcaster RAI, the privately owned La7 and Sky plc's Sky Italia.
Mediaset's headquarters are in Milan, Lombardy. Many of its studios are located in the Milano 2 area of Segrate, a municipality bordering Milan, where broadcasts of local station TeleMilano (now airing nationally as Mediaset's Canale 5) began in 1978. After merging with various local broadcaster to form the Canale 5 syndication, much production was moved to Cologno Monzese, where the infrastructure of the former Telealtomilanese was present. The company currently has three main television production centres, in Milan (Segrate, Cologno Monzese) and Rome.
Due to their proximity to (or encirclement by) Italy, Albania, Croatia, Switzerland, Malta, Monaco, Montenegro, San Marino, the Vatican City and Slovenia also receive Mediaset broadcasts.
In addition to its domestic television interests, Mediaset also operates a series of news, entertainment and sport websites; holds 50.1% of the Spanish broadcasting firm Mediaset España Comunicación; owns the film production company Medusa Film; and heads a consortium which owns the television production house Endemol.
