IBM is 100 today.
It was first called The Computing-Tabulating-Recording Company. For many years it was the world's largest technology company, and five of its employees have won Nobel Prizes.
In the 1980s 'Big Blue' lost billions of dollars due to failing to keep up with the progress of technology and was returned to profitability only a decade later.
IBM has always been a champion of workers rights and was one of the first companies to give equality to black workers and women.
