Every innovation begins with a dream. No matter how utopian this dream would seem to be, there is a high possibility that one day, this dream may become reality. Obstacles, difficulties and temporary lack of knowledge all combined may be powerful but when sheer fascination of the particular subject is involved, everything is possible. Back then, in the 1970s not many people would believe that one day popular typewriters will be replaced by an extensively more modern device. Computers required plenty of space in a room and they had to be stored in specific conditions. As exclusive machines, at the very beginning computers were used mostly at prestigious companies and for military applications and no signs of changes in this field could be noticed. It all has changed with a dream of two very young men interested in modern technology when the history of Microsoft was born.
