So I've been adding the viewer numbers to the chronology category for the different series. Sometimes, an interesting thing is revealed. But in practical terms, it mostly means being disappointed in Japanese children.
Now before I get into this, I feel like it's important to remind people that a higher viewership doesn't mean that the show is better. All it really means is that for that time slot, this many people watched this show compared to other shows occurring at the same time.
(There's a summary of the viewer numbers at the bottom showing average, highest viewed episode, and lowest viewed episode)
