Historically one of the most important inventions, which has become crucial in the evolution of the condition and of human communication is undoubtedly the radio.

Perhaps much more than television, which actually represents an evolution of the radio itself, the radio since its inception has succeeded in a goal unthinkable at the time: a reference point for the immediate information and entertainment.

Surely the golden age of radio can be found around the 50s, after the Second World War, during which the radio had become the sole source of information for many families and many radio stations as Venetian, Venice, London had become the only realistic source of information and news about the status of submitted and the situation of the partisans who fought in secret.

In Italy it is the radio after the war that lives her greatest thanks to the exponential development of the RAI, which is the Italian Radio Hearings, and the sharp fall in the price of these devices can be purchased at virtually all Italians. In 1951, transmitted the first live radio fm of the Sanremo Festival and since then the radio will become the central vehicle for public opinion and the widespread dissemination of information and trends. Are suddenly created three public radio stations, National, Second and Third and at the same time is adjusted the frequency of the radio log, which must be equitable from the outset and monitored by the special Commission.

In 1954 with the introduction of mass television, radio is to have a function and a placing more niche reserved for certain situations like a car, this time the invention of the car transported in local youth, see portable radios and much more that has allowed the unit to withstand time through the change of form, but not the substance.

Until the late '60s, the radio has always been the prerogative of the RAI by law but with the student protests and all the revolutionary period that accompanied the 68 born Italian private radio stations that broadcast programs aimed specifically at young people called Rome 3131 and officially RAI's monopoly ends in 1976, kicking off u great creative period for the radio that sees many local radio stations at a speed very exciting. Suffice it to say that the number of radios increased from about 150 in 1975 to 2800 in 1978!

In the 80 spreads, however, another principle that private radio stations, because of the advertising revenue of the broadcasters then calculate the importance of radio and music not only on the information provided but also on the amount of listeners .

The first private radio station in Italy and Radio Deejay, recorded in 1981 by Claudio Cecchetto and to follow Radio Italy and Radio Italy Network. The following year the RAI launches two more channels that instead of aiming points to entertainment magazine programs.

After a period of crisis in the late '90s, due to the introduction of new technologies such as mass mp3s, radio is seen reborn with the introduction of player that allows streaming of music directly from the PC, and then at any time of day, not by chance that all radios are now focusing on digital music, as well as many broadcasters are born directly on the web, in short, a new round of free radio stations!
