They've always lived in their own little world without any perception of what's appropriate in terms of what's going on in society and even the public mood. I remember when Diana died, all the cable channels such as MTV and various lifestyle channels ceased broadcasting and had a card up saying something about respecting current events. Q kept going, oblivious to it all until their sales must have reached zero and they finally suspending broadcasting, around the Thursday of that week.
I read an interesting article in the Guardian about what will happen when the Monarch dies, something few of us at this point, have experienced in our lifetimes. It's know as
London Bridge Is Down and it's an interestng read (albeit quite sobering and somewhat morbid). I expect QVC will be excempt from all of this, it wouldn't surprise me if, like the broadcasters who regularly rehearse their prepartions for such an eventuality, they have a stock of commorative memorabilia ready to start peddling, in their own "respectful" way of course.
