Think (IBM) - Wikipedia
"THINK" is a slogan first used by Thomas J. Watson in December, 1911, while managing the sales and advertising departments at the National Cash Register Company.[1] At an uninspiring sales meeting Watson interrupted, saying The trouble with every one of us is that we don't think enough. We don't get paid for working with our feet — we get paid for working with our heads. Watson then wrote THINK on the easel.[2]
Asked later what he meant by the slogan, Watson replied, "By THINK I mean take everything into consideration. I refuse to make the sign more specific. If a man just sees THINK, he'll find out what I mean. We're not interested in a logic course."[3]
In 1914, Watson brought the slogan with him to the Computing-Tabulating-Recording Company (CTR) and its subsidiaries, all of which later became IBM.[4][5][6][7] International Time Recording, one of the subsidiaries, published a magazine, Time, for employees and customers that, in 1935, IBM would rename THINK.[8][9] IBM continues to use the slogan.[10] THINK is also an IBM trademark; IBM named its laptop computers ThinkPads and named a line of business-oriented desktop computers ThinkCentre.
"THINK" entered the popular culture, often in a humorous context.[14]
