10 years ago, a person would be insulted for filming a video in portrait instead of landscape. Now, old landscape videos are being cropped and resized to fit in a portrait player.
Every time I see someone film vertically I send them this YT video /watch?v=xL23Xvv1Pis (was not sure if I'm allowed to post links here). I just think it's a brilliant and underappreciated parody.
TBF I kind of got used to portrait videos but I still block YT shorts and alike as most videos in that format are garbage anyways.
