Emulation when I was younger (and to a lesser extent now. I own the vast majority of old consoles/games I have any interest in playing these days). These days it's near exclusively TV/Movies and pretty much entirely because of convenience. Between myself and the others in my household, we have near every streaming service, I just can't be fucked to figure out which one what I want to watch is on.
I really need to get around to turning my old pc into a media server.
