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.

the problem with that, and a big reason why it probably won't be adapted, is that portrait mode shows you fuck all, it's good for showing one person (you know like a portrait) but if you want to show multiple people you have so much deadspace top and bottom. Landscape is just aesthetically better
