Google went live in 1998, revolutionizing the way in which people find information online.

In 1996, HoTMaiL (the capitalized letters are an homage to HTML), the first webmail service, was launched.

Facebook launched in 2004, though at the time it was only open to college students and was called "The Facebook"; later on, "The" was dropped from the name, though the URL http://www.thefacebook.com still works.
