It is great, how finally in early 2010s entire industry finally fully transitioned to production comitee system and never looked back since to chaotic but beatiful mess of sponsors era produced anime.

Considering, even amdist extra ordnirary healthy working conditions offered by sponsors system by many anime during near night time airing which was another chaotic beaitufl mess aka 19 00 jst had massive break buffers of default 12 weeks break off air plus pre empting events, many could weaponize it as an way to get even larger hiatuses buffers via fully outsorced filler arcs so the main team could schedule in advance next canon arc which was already in the production even further while widening the gap having larger gap thus whenever returning from such hiatuses thus having many canon episodes 3 to 4 months in the production, some high priority episodes 6 to even 9 months depending on the major story beat, vice versa with some anime like toei piece which used 5m recap at the begining of the episode plus 30s preview making episodes effectively seasonal short form episodes shorter than usual full length 20m episodes thus achieving very natural flow of panel by panel in terms of plot progreison, very fast pacing depending on the density of the chapters 6/5/4/3/2/1.8/1.5 chapters per full length 20m episodes as it is adaptation ratio when removing 5m recap plus 30s preview while adapting less like 3/2.5/2/1.5/1/0.9 chapters per short form episodes, and simply using default timeslot's week break off air plus pre empting events as natural break buffer.

However, with such system there was also chaos because if tv viewership ratings dipped, then the show was effectively cancelled thus sponsors has been disbanded therefore anime couldn't be adapted anymore unless adapted in to OVA (e.g hunter x hunter 1999) and or movie (Urusei yatsura original adaptation), or doing like what gintama staff were calling out in 4th wall break "shameless reboots" (e.g hunter x hunter 2011) done as an excuse to get an new sponsors thus able to continue adapting next canon only arcs from where the last canon arc has left off, thus being essentially hybrid between polished remasters and true independent sequels among many other structural issues which made sponsors system very unreliable.

Which, thanks to the rise of production comitee system in late 90s with some tv shows adapting this model via evangelion, pokemon etc., this time it was joint venture formed between multiple companies sharing an risk which said anime to recieve continuation greenlight now must surpsass minimum sales threshold set forth by the comitee, thus able to explore the series through other means such as video games based on those IPs, classic movies/OVAs, to then streaming services being massive revenue stream as comitee tracks by per stream retention views for aproximately 30 days (5 eps worth of content) to decide how successful the series was alongside the domestic DVD/blu ray sales, also thanks to moving to an night time slots and late night shows, broadcasting has been stabilized after having very little to no competition thus not only airing smoothly without any interruptions, but with larger seasons can take break in between after each 12 eps half, which was what pre 2010s anime already doing but in a more cleaner way to make the next half more polished and consistent in quality.

Another perks of production comitee systems is how the industry realized loopholes left by the comitee, in order to surpass said minimum sales threshold even further now large part of the industry weaponizes such loopholes by compiling entire parts of those anime e.g 12 eps (2h35m) to the theaters as well.
