What is the yellow tag category called?

The category with tags like pokemon, paw patrol, undertale, the lion king, my little pony, etc… I tried searching on the Tags page with category:franchise, category:series, category:copyright, category:origin (which I found is the purple category mainly for artist and director tags), and I ran out of ideas.

Here’s the list of category names:

⁽¹⁾ Tags with namespace prefixes are assigned to that category automatically, otherwise, the category must be assigned manually
