>>58700495>Damn, has pokespe always run concurrent arcs side by side?Since 2004. Pokespe's serialisation back then would be several chapters spread out across several magazines often not in order, the volumes would then chronologically collect the chapters.
For RB until RS' first year and a half or so, things were this year and pretty linear. The only odd discrepancy is Blue telling Silver to look out for Lugia was actually the beginning of GSC's magazine run bundled with VS Murkrow, not the end of Yellow as depicted in Volume 7.
Anyways, when FRLG came out, they decided to make a schedule where it would come out on only one magazine on a monthly basis. This allowed Kusaka and Yamamoto to still focus on RS and put aside time for FRLG. Then in 2005 they started Emerald (which was called Battle Frontier Story in the magazine run) in another magazine, which meant RS' rate crawled to a half of what it was in 2003. Anyways, The gen 3 arcs began to slowly end their magazine run towards summer-autumn 2006 while DP started with a more frequent schedule. The Gen 3 arcs would be completed as the volumes caught up across 2007 & 2008. DP got collected into volume form by late 2008. For most of 2009, it was the first time since RS where the volumes and magazines were on the same arc and not too far behind.
Pt-BW begin in 2009-2010 and that's when what happened in Gen 3 happened again, because the volumes were still at 37. What made this situation worse, however, was Grade Magazine n which slowed everything to a halt. HGSS was unceremoniously cut off very early on and rushed itself for the volumes to catch up. Meanwhile, BW slowed to a halt. This leads to the mini-volume shitshows and the Gen 5 hiatus.
TLDR: Since 2004, but it got untenable in 2011.
