When Thomas J. Watson joins the Computer-Tabulating Recording Company -- the forerunner of today's IBM -- in 1914, he brings with him the "Think" motto he coined when he managed the sales and advertising departments at the National Cash Register Company. "Thought," he says, "has been the father of every advance since time began. 'I didn't think' has cost the world millions of dollars." Soon, the one-word slogan "THINK" appears in large block-letter signs in offices and plants throughout the company.
