I think one major network in the US is 720p60, but the vast majority of broadcast transmissions globally is 1080i25 or 1080i30*
Of course sadly so much content is produced at 1080p24 nowadays for that “film” effect it’s rather meaningless for display purposes.
Online of course it tends to be p50 or more commonly p60 (even in 50hz countries). YouTubeers tend to be able to afford more lights and clearer microphones than big budget productions too.
