Mention that viewers often search for "M6 ce soir 21h" to check the program, teasers, and special segments. Then, maybe a section on what's typically in that slot? Wait, but also include the context given, like the bande annonce promos, the appel à témoins, the news segments? Wait no, wait the context has some stuff: BA promos, dates, the appel à témoins for M6 ce soir 21h, the news summary about the Russian strike, drones, Black Sea? Wait no, wait let's make it accurate.

Mention that these BAs are dated, usually released days or weeks in advance, to build anticipation. Wait the context has links like lc.cx/Mmsl35, right?
