(The) FNN, the Federation New Network (emblem), has appeared in several #StarTrek episodes so far ( #ShortTreks "Children of Mars", #StarTrekPicard's "Remembrance", #StarTrekLowerDecks' "Grounded") and now is also seen, slightly changed after 800 years, in #StarfleetAcademy's "Vox In Excelso". I can confirm that FNN did not appear in "Star Trek: Generations", as I did extensive research on that:
