1943: The birth of Mark I Colossus
More than 70 years ago, this top secret project arrived and helped to win a war. It sounds like a science fiction story, doesn’t it? The Colossus machines were the first electronic calculating devices. They were used by the British to read German encrypted communications during World War II. This means that the Colossus, originally designed by Tommy Flowers, was one of the first digital computers. -

1954: First prototype of desktop calculators
Back in 1954, IBM presented the world’s first electronic calculator in the United States, made with transistors, something highly revolutionary and technological for the time. It was quite large and could cost around $80,000. But, after a short time, more commercial models were launched, which thanks to the development were more reliable and affordable. -

1969: The creation of ARPANET
ARPANET was just a small network of computers that was created on behalf of the United States Department of Defense. They did so as a way of communication for the various agencies in the country. We are witnessing the seminal net that would become what we now know as the Internet. In 1990, ARPANET ended its existence. -

1971: The first e-mail is sent
The first e-mail was sent by Ray Tomlinson.As a curiosity, he used for the first time the @ symbol between the user name and the machine. This fact is now a thing of the past, as you can imagine. He chose this symbol because, he explained, “it certainly wasn’t in a real name”. Ray’s heart must have been broken because he received no response…. The innovation was so innovative that since it was the only program installed, there was no opportunity for dialogue. -

1981: IBM launches a PC
IBM achieved a milestone in the history of humanity in general and of computing in particular: with the commercialization of the personal computer, or PC, it managed to turn computing from being a hidden mystery for the majority, to becoming something useful and practical for everyone. I assure you that neither prophets nor seers could have imagined the revolution that this would entail today. -

1990: Tim Berners-Lee writes the first website
And here’s the link: http://info.cern.ch/hypertext/WWW/TheProject.html It was exactly on December 20, 1990, when Berners-Lee, a British scientist, uploaded this page to CERN’s servers, with the mission of explaining the basic principles of what the modern web was going to be. As you can see, it is a simple page with rudimentary text and hyperlinks. This is a modest guide on how his project would work. -

1997: The machine defeats the man, in chess
The event took place in two parts, the first in Philadelphia on February 10, 1996, where the IBM Deep Blue supercomputer faced the then champion, Garry Kasparov. In the first game, after an initial fright, the great master ended up winning. Humanity could continue to breathe in peace. But IBM prepared the rematch. It was held shortly thereafter in New York City in 1997. In that historic duel the machine won. -

1998: Google was founded
In 1997, they decided that the BackRub search engine needed a new look and feel and considered some ideas, including a game of the word “googol”, a mathematical term represented by the number 1 followed by 100 zeros. In 1998, the then co-founder of Sun, Andy Bechtolsheim, prepared a check for about $100,000 for a newly registered company, a certain Google Inc. that would make us all happy. -
