LCI was launched on 24 June 1994 by Christian Dutoit on behalf of the media group TF1 as a pay television channel. Its launch was also simulcast on TF1.
The broadcast began at 8:30 pm with the live TV news program presented by Françoise-Marie Morel. The first guest was the CEO of the channel, Étienne Mougeotte.
The channel was also broadcast in Italy alongside TF1 on digital terrestrial television from 2004 to December 2006 on Dfree multiplex.
In 2006, the channel's website appeared twice in the James Bond film Casino Royale, a product placement that the channel says it did not pay for.
On 5 April 2016, the channel became free-to-air and began broadcasting on channel 26 via digital terrestrial television in France.
