«Chaîne Nationale» was the first national television service in France, commencing its broadcasts in 1935. The channel was originally known as the "Télévision Française" and operated under the control of the French government.

The initial broadcasts were experimental and limited in scope, featuring demonstrations of the technology and basic programs. As the technology advanced and the audience grew, the channel expanded its programming to include a variety of genres, including news, documentaries, and entertainment.

«Chaîne Nationale» played a significant role in introducing television to the French public and contributing to its development as a medium. The channel was a major source of news and information, and it also played a role in promoting French culture and arts.

The channel underwent a number of changes over its history, including changes in its name and ownership. In 1964, it was renamed to "Première Chaîne" and became part of the national television network "Office National de Radiodiffusion-Télévision Française" (ORTF).

In 1975, ORTF was dissolved, and the "Première Chaîne" was replaced by a new channel, "TF1", which continues to operate today as one of the major television channels in France.
