Clips from movies and TV shows become popular on TikTok, Insta, and YT shorts. They drive interest into seeing the full movie or series. It's viral, free advertising.This is such an odd move to me. Maybe I’m too old to get it but is there really a big enough demand for streaming services to have a TikTok feature?
Disney just made a deal with Open AI for people to use assets from their movies (but not real life actors' faces or voices) to create their own shorts that will show on D+.
So... "vertical videos" were already underway even before this announcement.
