International Business Machines is a master of adaptation and renewal. What started as a merger of time-clock manufacturers in 1911 eventually brought us the mainframe computer in 1949 and the first PCs in the 1970s. IBM sold its PC business to Lenovo in 2005 to concentrate on consulting and software services.
Today the company is transforming again, moving into cloud computing, artificial intelligence, and Blockchain applications. The latter includes food safety as well as initiatives that speed shipments of goods and bypass slower international payments systems with simultaneous clearing and settlement options.
