How did television change from black and white to colour?

Black and white television has long been part of history. But do you know his story, and do you know when and how the transition happened?


On April 26, 1935, under the impetus of Georges Mandel, then Minister of Posts, Telegraphs and Telephones, the first official French television broadcast was broadcast from the Ministry of PTT, located rue de Grenelle, in Paris. The image, in black and white, uses a process developed by Henri de France. At the time, there were about 100 television sets in French homes (currently, more than 98% of French people were equipped with a television set).

From 1940 onwards, French radio and television broadcasting was under the control of the German authorities in the occupied zone.

On October 1, 1944, after the liberation of Paris, television programs were broadcast in closed circuit in Cognacq-Jay’s television studios, created under the Occupation. It was only at the end of 1945, after the Eiffel Tower’s summit had been returned to the French authorities by the American troops who had commandeered it, that television broadcasts resumed, still in black and white.

On 8 February 1949, the Radiodiffusion-Télévision Française (RTF) was founded, a public establishment under the authority of the public authorities and with a monopoly on radio and television broadcasting in France.

The first television news programme, created by Pierre Sabbagh, was broadcast on 29 June 1949. The filmed news are commented live and in “voiceover”. The team is composed of personalities who have made history such as Gilbert Larriaga, Pierre Dumayet, Pierre Tchernia, Jean-Marie Coldefy, Georges de Caunes, Denise Glaser, Jacques Sallebert, Roger Debouzy, Claude Loursais, Claude Darget, Jacques Anjubault.

On that date, three thousand televisions were installed in private homes.

The Office de radiodiffusion-télévision française (ORTF) was created in 1964, replacing the RTF. This reform aims to modernise the school and give it more autonomy: the ORTF is now placed under the supervision of the Ministry of Information, and no longer under its authority.


It was in 1967, on the 1st october, that French television programs could be broadcast in colour, and received as such by households equipped with adapted televisions. This transition from black and white to colour is done live on the 2nd channel, which was created in 1964.

The first colour broadcast features an address by the Minister of Information, Georges Gorse, surrounded by Claude Mercier, Director of Equipment and Operations, Jacques-Bernard Dupont, Director General of the ORTF, and Émile Biasini, Director of Television.

TV 4K, what is it? Should we buy it?

You have probably often encountered the term TV 4K but do you really know what it is about? Want to know more about this new technologie ? And what are the real benefits for utilisateur ? This article will allow you to deepen your knowledge of 4K TV.

4K, 4K Ultra HD, Ultra HD and UHD. All these terms are often used instead of each other, but basically they all mean almost the same thing. Strictly speaking, 4K and UHD are not synonyms: 4K resolution is the professional cinema standard while UHD refers to consumer screens and the type of broadcasting. Because this difference is not very important for consumers, we will not dwell on this subject.

To put it simply, we are talking about the successor to Full HD TV, a resolution that until now has represented the highest quality of the visual experience. There is a good chance that you will have a Full HD TV at home. But evolution never stops. That’s why today, 4K supports up to 4 times more pixels than Full HD. At Samsung, we call most of these TVs Ultra High Definition (UHD) TVs.

TV 4K: a resolution for large screens

The 4K TV offers 4 times more pixels than the HD TV. This makes it a very interesting solution for large screens. Are you thinking of buying a Smart TV with a screen larger than 48 inches (121 cm)? Then chances are that the “simple” Full HD is no longer enough for you. Of course, it also depends on how far you are from your TV.

You can therefore decide to switch to a 4K TV. It will allow you to enjoy a more detailed picture. Applications such as Netflix and YouTube already support this format and, soon, all content will be delivered in this format. More and more other services (streaming) will share their content via the 4K format in the future.

This month, the first films on Blu-ray 4K Ultra HD have made their appearance. A new image format considered a real must by all film lovers. Note that you will also need a new Blu-ray player that supports 4K resolution.

Advantages of the 4K TV

The advantages of the 4K are therefore obvious. Potentially sharper images have more detail. The viewing experience is even more intense, the cinematic pleasure even greater. The quality of older films converted to this format is far from the quality of the source material. The films recorded and broadcast on Blu-ray 4K will offer an absolutely incredible visual experience. On condition of course that you watch them on a high-performance 4K TV!

Upscaling to TV 4K

In addition, it is also possible to obtain better image quality from existing movies (including Blu-ray and streaming videos) by using the upscaling function of your 4K device. It will never be real 4K equipment but the active technology here remains very impressive and gives your movie collection a new dimension.

Do you need a 4K TV?

“Need” is of course a big word. No, you don’t really need the 4K. But by investing in a 4K TV, you move forward. Like when you went before a few years ago with a Full HD TV. But if you’re a true cinema enthusiast who wants to get the most out of every visual experience, then the 4K is for you. And by buying your 4K TV second hand, the budget can even remain affordable for unparalleled quality! As we said, the first 4K Ultra HD Blu-ray movies have appeared!
