So I have noticed unfortunately that written media has become something large swathe audiences are turning away from, and having spent 20 years building my world I am hoping to share the tales of my world with as many people as possible, I was hoping that maybe people may have some decent insight on this? Perhaps good mediums on youtube to advertise such. Should I do longform stories first? shorts to grab the attention? I'm brand new to the youtubing thing and any and all information would greatly be appreciated.

For context: It's a high fantasy style story(ies) delving deep into the characters, the lore of the world Terra IV as well as maybe inspirations of it if it gains enough traction. :)
