Just people in the public spotlight...celebrities...humans love to watch what others in that position do, the drama, the pomp and circumstance.
At least there is a lot of history and tradition in the UK. I took some tours when I was there a few years ago, some neat stuff! But these days it's just another celebrity, like a Hollywood actor, pretending to be something bigger.
If you're asking for my opinion, the people that REALLY get into that stuff just don't have enough going on in their own lives. It's easier to watch others "do" while you sit and do nothing.
