This is Arpanet. The internet before Google. Before Flickr, before YouTube, before Chatroulette, before BitTorrent. Before pictures of your ex-girlfriend on Facebook. An internet that you could draw a map of with only a few lines and some dots. 1972.
At this point, the internet wasn't even the internet - still dubbed ARPANET, the Pentagon (and a handful of universities') private plaything. As you can see, it wasn't exactly... extensive. The network served only to link key research centres. It's pretty amazing to think that this smattering of cables turned into the bizarre, twisted, incredibly complex nebula of porn, parody, knowledge hatred, joy, and cat videos we now adore. [Life]
