Are all those things indeed decreasing quality, or are we all getting old and missing those "old times"? As teenagers we definitely had different expectations from newspapers, music, life in general... maybe we are just not their target anymore.

Yeah, in France I grew up on Geo.

Then National Geographic showed up when I was teenager but it started to enshitify rather quickly with sensationalism and cliffhanger.

Just this year the publisher of GEO (Gruner+Jahr) axed most of the special edition series of GEO like GEO Wissen and GEO Epoche.
