drop in views after changing content

im an editor and i was mostly editing star wars, marvel and dc but now i want to post primarily anime. my posts would get 30k+ on every video.

i changed my content to anime overnight and now my videos are getting under 1k views. i understand this is because i had a completely different audience and they aren’t used to that type of content.

i guess my question would be if anyone has done overnight content changes and could maybe give some advice on how i can reach anime viewers instead of my old content viewers.

also how long i would have to be in this run of extremely low views. i really want to move on from my old content but seeing such low views is also discouraging.

Thank you in advance.
