  2. August 1960 • On August 12, 1960, the world’s first communications satellite was launched into space. Launched by NASA, the satellites name was Echo 1 and its means of getting into orbit was by simple balloon floatation. It was able to soar 1,000 miles above the Earth, and relay signals to certain points on the planet.

  3. December 1960 • AT&T created the first commercial modem called the Data phone. It was specifically used to transmit and convert digital computer signals to analog signals in order to improve communication across long distance networks.

  4. 1969 • Bob Kahn created the first version of the Internet in 1969. His version of the Internet was much smaller though and was actually called, Arpanet, during this time. Arpanet was able to connect four different computers located at the colleges of UC Santa Barbra, Standford, University of Utah, and UCLA. Arpanet was created out of the necessity for transporting sensitive military data to and from different locations. Therefore, Arpanet was created to satisfy those needs.

  6. 1971 • Ray Tomlinson sent the first email in 1971. It was sent over a military network called The Advanced Research Projects Agency Network. Tomlinson is credited with being the one to decide on the "@" sign for use in e-mails. When Tomlinson was asked what was in his first email, he said it was "QWERTYUIOP." Tomlinson did this while he was supposed to be working on a project for BBN (Bolt, Beranek and Newman) Technologies

  8. 1981 • In June of 1981, the Osborne 1, which was the first ever-portable computer, was created Adam Osborne and Lee Felsenstein. For its time, the Osborne one was a hallmark in computer technology and innovation. It sported a 5” screen capable of displaying 52 characters of text in one line, contained 2 floppy disk drives and a detachable full sized keyboard. However, there were some drawbacks. For example, the computer wasn’t exactly that portable, weighing in at 24 pounds and being the size of a small suitcase, it didn’t really live up to the “portable” part in its name. Nevertheless, it was a true testament to human ingenuity and innovation, and forever paved the way for the portable computer.

  10. 1988 • The first documented computer worm was recorded in 1988, which was coded by Robert Morris, son of a computer security expert for the NSA. This “nondestructive” worm that Morris called it caused problems for 6,000 of the 60,000 or 10% of hosts linked to the ARPANET network. Morris was sentenced to three years of probation, 400 hours of community service, and a fine of $10,050. Morris said that he was motivated out of boredom.

  12. 1990 • The World Wide Web (www) was born in 1990 when Tim Berners-Lee created Hyper Text Markup Language (HTML). A browser such as Microsoft's Internet Explorer was used to follow links and send a query to a server allowing the user to view a site. Berners-Lee's goal was to allow people to work together by combining their knowledge in a global web documents. The first World Wide Web server and browser was available to the public in 1991.
