Licensed character series start out life basically in one of two ways: as characters in books or as characters in products, TV, apps, or other media.
When they become popular, they’re licensed (loaned out for a price) into other media and products. When a licensed character or series of characters becomes so popular and gets licensed into so many product categories (bedding, stationery, toys, and so on), then it becomes a brand. That’s just a fancy way of calling a licensed character a product instead of just the star of a book or TV series.
