The anime industry has changed massively over its long and storied history. If you took a modern anime creator back to the 1950s or brought a 1950s creator to the present day, they likely wouldn't recognize the industry due to how it has transformed over time.

One older concept that has been coming under increasing scrutiny in recent years is the idea of anime seasons, but is it time for this format to fade into the past?
