It’s debatable for me when the Internet actually started. Some say it was way back in World War II. Some say that CERN invented it, and there’s a million other stories of how the internet started, just floating around on the web. Well, the first domain name ever was Symbolics.com, which is now a blog. On this day in 1985, it became the first registered domain name on the internet. Now the internet is completely overrun by dot com domains, which is why we see .org, .info, .xxx, .eu, whatever.
Whenever it started, the Internet has made a huge difference in the world, both good and bad.
