Like many broadcast journalists I have far too many anxiety dreams about equipment going wrong during a live programme.— Tom Hourigan (@TomHourigan) February 24, 2021
So imagine *all* your equipment failing. All of it.
And having to tell the audience of France’s most watched lunchtime news that there won’t be any news 😮 pic.twitter.com/f4yhjxk1tG
Can read a dramatised version of what happened in the Express... https://www.express.co.uk/news/world/1402091/France-news-France-TF1-technical-blunder-moment-Marie-Sophie-Lacarrau-vn
...or find out actually what happened in French newspaper La FIgaro https://tvmag.lefigaro.fr/programme-tv/panne-au-13-heures-de-tf1-les-vraies-raisons-du-bug-technique-revelees_0c07f986-7695-11eb-9ea8-48b0d7a02ee9/
LCI also had issues as they share the same system as TF1.
There are also rules against live TV simulcasts in France; they can transmit France 2's 8PM news on France Info an hour later, but not at the same time. Apparently though, they can transmit something on TV and radio simultaneously. France Info's short summaries are done this way. It's interesting that TF1 didn't even improvise a quick summary.
