Today I spent some time hacking together an ownership graph of Australian newspapers. Spoiler: it’s all owned by News Limited and Fairfax, but click on the pretty picture below and you can see exactly how stuffed it is in an ugly interactive physics based format where you can click and drag stuff around.
Arrows indicate ownership of course, with X–>Y meaning that X owns Y. You can see the code if you want. I might make it less ugly in the future but for now, it is what it is.
