I have now finally been using the Internet for more than half its existence. That's 20 of its 40 years. Back in 1969 the first few bytes were sent between networks (hence the name, it was a network of networks) as part, believe it or not, of a plan to save money. The BBC has a nice article about it. The Globe and Mail tosses in a quick summary of the history of the internet, which reminds me to link to my post that points to a more comprehensive summary in Vanity Fair.
If you think the Internet is just the web, all I can say is you missed a golden age. These days it's always September. I know I prefer what we have now, just as I can still miss what we had then.
