Luxembourg played a pioneering role in the European radio landscape. In the 1930s, at a time when the radio landscape in Europe was still characterized by a public radio monopoly, the Luxembourg government recognized the potential of this new technology and granted broadcasting licenses to private radio.
In 1931, taking advantage of this multitude of assets and government support, private investors launched the Luxembourg Broadcast Company (CLR), which today has become RTL Group, the first European audiovisual group.
In 1991, the law on electronic media opened up frequencies to competition.
This law establishes various categories of radio programs, with some falling under the jurisdiction of the Luxembourg Independent Authority for Audiovisual Media (ALIA), namely local radios and network broadcast radios, while others are under the jurisdiction of the Government, such as high-power transmitter programs, as well as international broadcasting services, Luxembourg services via satellite, and Luxembourg services via cable.
Then, in 1993, the public radio station 100.7 was established.
Since the liberalization of the airwaves in 1991, the number of Luxembourg-licensed services has steadily increased. Today, there are several high-power radio services, network radio services and local radio services.
Similarly to the landscape of print media, the radio landscape in Luxembourg is characterized by multilingualism. However, the Luxembourgish language remains predominant in relation to other media.
