Hmm, not familiar with the connection. I stumbled across it while roaming Wikipedia. Origins are unknown possible from “Samiel”, the name of the Devil in some opera. Or Sam Hill, a man in the 1800s known for using such foul language that his own name became a swear. Imagine that. While most strive to leave their mark on the world by leaving something good behind or raising good kids or helping someone in a life-changing way or whatever, he left behind his own name as a swear.
Vertical live streams? As in camera orientation? Vert videos will have this feature and horizontal won’t? Not knowing the intricacies of the content creator world, I don’t get why vertical vs horizontal should make any difference.
