>>55468211I think the difference is that from 96 to 2000, Pokemon was THE children's thing between Japan and the west, like Power Rangers or TMNT before it. The public wanted to know everything about it, even if they weren't interested in it (see: all the satanic panic scares about Pokemon featuring evolution). So with people covering it, more information is available because people were asking questions. Sometime during Gen 2 that fell off, and people often blame the Johto anime for sucking, or the transition to GBA and the isolating of Gen 1 and 2 Pokemon, but mostly it was just the transition into the new cool children's thing (Yugioh, maybe, I dunno). Aside from Shudo's blogs and the Hidaka interview from 2008, Pokemon history really seems to end between 2000-ish and 2016 when PoGo came out.
Picrel is from a French book I got sometime last year when I was (re)watching the anime. I give it credit for actually providing summaries of what happened in the anime/games between Gens 3 and 6 (it was released pre-PoGo), but then I looked at the sources they used and...well, that's the news.
