The WWW (World Wide Web)

Tim Berner Lee found it frustrating that during earlier days, there was different information on different computers, and one had to logon to different computers to get the desired information. Sometimes he had to learn different programs on each computer. Therefore finding out how things worked was really difficult and cumbersome.
He was associated with CERN (European council for nuclear research, world’s largest particle physics lab situated in Geneva). Since lot of people at CERN came from universities all over the world, they brought with them all types of computers. Not just Unix, Mac and PC: there were all kinds of big mainframe and medium sized computers running all sorts of software.
To resolve the problem he actually wrote programs to take information from one system and convert it so it could be inserted into another system. According to Tim Berner Lee, “when you are a programmer, and you solve one problem and then you solve one that's very similar, you often think, isn't there a better way? Can't we just fix this problem for good? That became ‘Can't we convert every information system so that it looks like part of some imaginary information system which everyone can read?’ And that became the World Wide Web” – a system that has revoultionised the way we work and conduct our businesses.
