Filodiffusione is a cable network created in 1958 thanks to an alliance between RAI and SIP (the Italian National Telephone Company).

At the time of its first transmission, on January 4th 1959, Filodiffusione was using telephone lines to broadcast three already operating Radio Channels, and two specifically created channels (IV and V) , specializing respectively in popular and classical music (broadcasting now 24 hours a day.)

Channel IV transmits a large selection of Music, spanning from pop, rock, fusion, jazz, to Latin American, movie soundtracks, melodic and easy-listening symphonic music, from the 50's until today.

Today "Filodiffusione" can be heard not only through the Telecom Network using a special decoder (reaching about two million listeners daily), but also through the satellite Hot Bird II, 13° East, (11.804,200 Mhz, polar. Y vertical)
