For my money, 'Niall Ferguson's Networld' is an excellent introduction into modern thoughts on the effects of networks on society with excellent applied network theory concepts presented.

Personally, I was very interested in the fractal aspects of networks which is not addressed being out of scope here, but that's neither here nor there, of course.

Until recently, most casual conversations about current television would arrive at the same conclusion: “There’s just too much! You can’t watch it all!”

That diagnosis is now being put to the test. But not only are the sequestered multitudes going to consume more television, they’re likely to digest it differently.

And there are few better examples of that than 'Niall Ferguson’s Networld,' out now via PBS. Focusing on the geopolitics of our interconnected world, with lessons from terrorism and surveillance, Niall Ferguson shows how our democracies are under threat from forces that exploit and weaponize the social networks that we invented.
