Almost 500 people are part of the Arkena organization.^[2] Arkena went out of business as company in December 2019 and after a management buy-out, Cognac-Jay Image took over.

Télédiffusion de France was created in 1975 as part of the split-up of the formerly-unitary national broadcaster Office de Radiodiffusion Télévision Française (ORTF) into seven separate organisations. TDF therefore inherited the ORTF's transmitter network and other technical assets, and from 1984 also provided broadcasting-related services to the French private TV channels.

The TDF Group created its media services division in 2004 through a combination of acquisitions and organic growth. Now, TDF Media Services regroups Arkena and BeBanjo.
