Mapping The Entertainment Ecosystems has already been blogged by John Gruber so you have already read it, so this is more for my own reference as anyone else’s.
In case you haven’t already seen it, Mapping The Entertainment Ecosystems of Apple, Microsoft, Google & Amazon maps the entertainment ecosystems – Music, Movies, TV Shows, eBooks and App stores – of Apple, Google, Microsoft and Amazon across the planet with some nice interaction HTML5 maps.
It makes for interesting reading/viewing. Note how absent Africa is from most of the maps apart from eBooks and Apps and North Africa is pretty much absent from all of them.
(And if you find that interesting, you’ll love Worldmapper – one of my favourite sites to explore data cartographically).
