Affiliate Marketing Secrets

I’m looking for a niche for my Media studies coursework.
Can you think/ know of any medical dramas (like BBC Holby city) aimed at children? The reason i’m asking is because I can’t think of any so this could be a gap in the market 🙂
thanks

It’s a long shot, but a few years ago I found a blog where the owner was conducting an informal children’s literature course over the summer through their blog. I have searched high and low for this, but have been unable to refind it. I am pretty sure that it was not affiliated with any college or university, just an opportunity for teachers, librarians and anyone else interested to learn more about children’s literature. If I remember correctly the background was gray or light brown. If anyone can offer any suggestions, I would be most grateful! Thank you!
