On October 6th, 1924, the first program (in Italy) of broadcasting was made from Rome,
exactly from Auditorium in via Maria Cristina 5. So it was proved that the
RADIO could have been also entertainment.
The exclusivity of the State on radio diffusions was established on November, 08 1924, with the possibility to be administered by private societies. The first concession was given on December 1924 for a period of 6 years to the society U.R.I. (Unione Radiofonica Italiana). It was immediately necessary to have a new adjustment of rules and laws. In 1928 a second concession for a period of 25 years was given the society named itself E.I.A.R. (Ente Italiano Audizioni Radiofoniche) and had to renovate all the installations and update all the programs. Since 1932 the signal of pause between programs has been the twittering of a bird. In the photo you can see the mechanism which generated the sound, used later also by R.A.I. (Radio Audizioni Italia), now Italian Radio television. |

A submarine of Regia Marina Italiana (Royal Italian Navy) was entitled to Guglielmo Marconi. This submarine disappeared during a mission in the 2nd mondial war in October 1941. The ship (see photo) was named Guglielmo Marconi in honour of the previous submarine. In 1960 the study on an atomic submarine started in Italy, but, after the decision of Italy to discard nuclear devices, the project stopped. In every case the atomic submarine would have been entitled to Guglielmo Marconi. Photo. Courtesy of: ........

When I look at the Moon, I think that the man landed and walked there and I realize that such a
venture would have never been in any mind without the radio. (Mimma)
Neil Armstrong, after he walked first on the moon, said "For a man this is a small step, but for
the humanity it’s a gigantic one". Guglielmo Marconi, hearing the legendary gun shot, could have
said the same words. (Ubaldo)
