But back to the topic. I'm sure that history class needs to add new events. High school physics might include a bit more detail about the shifting ideas about dark matter. But even if this is a critical age, I'm not sure why the old shows need to be replaced.
Also, this is like any other TV Show: there are X episodes done per year, there are production times, etc. This show has a pipeline like any other show.
And of course, there are important subjects that are a product of their time, for example: wouldn't it make sense to approach the topic of migrant families being torn apart in the USA due to extraditions, because children are going through it now? Or approach parents' unemployment due to government layoffs?
