Just had a thought. With most products, there's a brand that pretty clearly dominates, or vies with one other brand for the leading position, and then sales drop off rapidly as you move to the lower tier brands. Coffee=starbucks, soda=coke, beer is probably budweiser, console games = call of duty, facebook games = farmville. And that's awesome for the one or two companies in a leading spot and kind of sucks for everyone else - if the curves where shallower or linear-er more people could make a living creating a product that suits their own taste even if it's not the favorite, and there'd be more variety in the world, and more stuff to talk about. ("Have you tried this obscure brand of coffee? I really like it.")
And then there's wine. I have no idea what the leading brand of wine is - googling didn't seem to turn up a consistent winner - and I suspect that whatever wine does sell the most, it's not a juggernaut that's driving the other wines out of business.
Maybe I'm wrong. Maybe wines are under the same killer power law that all products have. If somebody out there could clear that up for me, I'd be grateful.
If I'm right, though, well, why is that? Why do wines have a flatter curve?
And then let me just take a moment to 'try the whine' and say, "Why can't games be more like wine?"
