The name "ThinkPad" is a product of IBM's corporate history and culture. Thomas J. Watson, Sr, had first introduced "THINK" as an IBM slogan in the 1920s. For decades IBM distributed small notepads with the word "THINK" emblazoned on a brown leatherette cover to customers and employees.[3] The name ThinkPad was suggested by IBM employee Denny Wainwright, who had a "THINK" notepad in his pocket.[4][5] The name faced disagreements from the IBM corporate naming committee because the nomenclature system for the IBM computers was then numerical; however, the brand name "ThinkPad" was kept as the press showed appreciation for the title.
