Synonymous with expertise and innovation in the field of broadcast, Thomson Broadcast is responsible for numerous developments that continue to shape the broadcast industry today. As part of its long-standing history, Thomson Broadcast was responsible for the first live radio transmission from the Eiffel Tower in 1937 under the name "Compagnie Générale de Télégraphie Sans Fil" (General Wireless Telegraphy Company).

As a driving force in its field, Thomson Broadcast has pioneered innovations in solid-state technologies including, Digital Adaptive Pre-Correction (DAP), Digital Radio Mondiale (DRM), and Digital Audio Broadcasting (DAB). All these have led to the success in winning multiple Emmy Awards and gaining more than 50 patents in technologies that have become fundamental in broadcast.

From 1995, Thomson Multimedia (TMM) specialized in consumer goods and later as Thomcast, leading the way to investing into the Thales Broadcast & Multimedia Division in 2005. In 2010, Thomson underwent a brief change in name to Technicolor, proceeding a separation from Thomson Grass Valley. Shortly after, Arelis Group emerged into the transmission and broadcast industries, focusing on Radio and Terrestrial Television transmission activities (including all patent rights) from Thomson Broadcast at the time of purchase. Thomson Broadcast is also formally recognized at Arelis Broadcast.

Since its integration into the Arelis Group, Thomson Broadcast continues to develop its product line and its experience as a world-leading manufacturer transmission systems and technological supports. Thomson has continuously built on its great heritage with its market leading portfolio of transmission products for terrestrial television, radio broadcasting and world class system integration services.
