It happened in 1990. Tim Berners-Lee, an English computer scientist, was working for the huge European nuclear research hub CERN when he found a way to make his fellow scientists more efficient. CERN researchers were using different computer platforms for work and they badly needed something that would facilitate data sharing among them.
Berners-Lee used the decades-old concept of hyperlinks and developed the first web server along with initial internet protocols and the first web browser. It took him two months to write the code that would change the world forever.
