I live in the EU, which is quite Americanized by any standard, and I'd bet nobody around me would recognize the name of Sean Hannity (or Nikki Haley, another name on the 2016 list). That list just seems hopelessly parochial to me.
It's a list of influential people, not most famous. Knowing who they are I'd say you could reasonably put both on such list.
What's Nikki Haley's influence on the world?
Being the US representative to the UN, I imagine she helped delay action on climate change and things like that.
She's only been the ambassador to the UN since 2017, yet she appears in the 2016 list.
Man, Trump really makes the years seem longer...
I live in the EU and know the cancer that Sean Hannity is. The global village is reality.
I live in the EU too and the only name that anybody would recognise there is Donald Trump because they spend all day on the telly telling us how evil he is. Also Hugh Jackman if you like his movies.
