TF1 is a French free-to-air television channel, controlled by TF1 Group, whose major share-holder is Bouygues. TF1's average market share of 24% makes it the most popular domestic network. Flagship series broadcast on the channel include CSI, The Voice and House M.D.
TF1 is part of the TF1 Group of mass media companies, which also includes the news channel LCI. It used to own the satellite TV provider TPS, which have been sold to the Canal+ Group.
The network is a supporter of the Hybrid Broadcast Broadband TV (HbbTV) initiative that is promoting and establishing an open European standard for hybrid set-top boxes for the reception of terrestrial TV and broadband multimedia applications with a single user interface.
TF1 (which originally stood for Télévision Française 1 (French Television 1)), was created on 1 January 1975 when law 74-696 7 August 1974 (which split the ORTF into 7 organisations) came into effect, and the rebranding from Première chaîne de l'ORTF to TF1 came into effect on 6 January 1975. A new multicoloured logo for TF1 created by Catherine Chaillet came out that same year along with cel-animated idents, and from 1976 until 1985 analogue computer-generated idents produced using the Scanimate system were used on TF1, created by the American company Robert Abel and Associates with background music composed by Vladimir Cosma. The 1975 TF1 logo was later modified in 1984 and again in 1987. Colour television were first introduced to TF1 on 1 September 1975 when FR3 (now France•3) agreed to supply some of its colour programming to TF1, and the conversion to colour on TF1 was completed in late-1977. Since TF1's privatisation in 1987, the abbreviation is no longer expanded, so as to avoid confusion with the government-owned television broadcaster France Télévisions. The channel was also broadcast in Italy alongside La Chaîne Info on digital terrestrial television from 2004 to December 2006 on Dfree multiplex.
