From my own perspective, as a mid-40’s UK male I now consume media and information on pretty much my own terms. I just don’t get any exposure to any of the characters mentioned in this thread unless I seek it out or, on rare occasions, on a forum like the dope.
All my TV watching is done via DVR or catch-up players such as the iPlayer. I don’t ever just stumble across reality TV, celebrity news or similar because they hold no interest for me, I’d never seek it out and would ignore it or turn it off if it appeared before me.
My news is via the BBC, Guardian, Independent and flipboard but again I’m only drawn to the articles that interest me (politics, sport, current affairs, science, history, natural world, art, film) so “gossip” passes me by. No physical papers or magazines
My wife and young children have no interest in any of the people that you mention so no familiarity by osmosis (though it works in reverse as my 8 and 9 year olds currently have cd’s of “Tommy” and “Rio” as music of choice)
My radio listening consists of BBC five live, Test Match Special and Absolute 80’s. When I get into the car after my wife has driven it there is a short period where I catch a minute or two of current music on her preferred station before I turn it over and I did come to know Katy Perry’s “Lion” song through that and thought it memorable enough to find out who sang it, but…nothing else has grabbed me. (and I couldn’t pick Katy Perry out of a line-up either)
I use Spotify, Pandora and Grooveshark (RIP) for my musical needs and their “similar artists” suggestions never take me to any of the musicians mentioned.
So it is no surprise that my knowledge of them is vanishingly small. I certainly know the names of Jay-z, Kanye West, Taylor Swift and Kim Kardashian but that is pretty much where my knowledge stops. I can’t put a face to any of them. I suspect that I’ve heard some of the music but none of it has interested me enough to find out who sung it. I couldn’t name you a Kanye West, Jay-z or Taylor Swift song and if you played one to me I might say that I recognise it, but knowing it was by a specific artist? No, sorry.
That’s just how the world rolls I guess. I’m better placed to filter out all the stuff that holds no interest and I have such a choice of media to consume that does interest me that the Ms. Swifts of this world are going to have to do something very special to get my attention. I got into British Sea Power and Mogwai just by hearing some of their work as TV backing music so I am willing to do some digging and hunt out the stuff that piques my interest but you’ve got to really interest me before I’ll go to that effort.
So no superior bragging of ignorance on my part. That’s a fair representation of how the world of celebrities, gossip and popular music flies way below my radar and I suspect that many others claiming scant knowledge of these characters are in much the same situation as me.
