anglais term (edited): nightly news program(me)

This kind of 'news programme' is what is commonly referred to as 'JT' (= 'journal télévisé')

I am astonished that people can 'disagree' with this as a possible solution, not least, because it is actually a term given in dictionaries for 'news', e.g. R+C:

news [Television] informations fpl , journal m télévisé

and also:

news broadcast, news bulletin: (bulletin m d')informations fpl, journal m télévisé

I think it is safe to say that 'news programme' is a synonym of those last two terms.

Please note that the same entry for 'news' does NOT give 'actualités' or any variant thereof.

I hasten to add, before anyone jumps in, that my knowledge of this term is not at all based on "what I read in a dictionary" — quite the contrary, it is based entirely empirically on my exposure to French as it is used every day in France. I only went to look it up in the dictionary because I was so intrigued by people's apparent rejection of the term.

Of course, you needn't use the acronym, you could spell it out in full as 'journal télévisé' — depends who the intended readership is, as to whteher you might prefer broadcasters' 'insider jargon' or a more general public term.
