as a U.S. trademark on June 6, 1935, with the description "periodical publications". This trademark was filed fourteen years before the company filed for a U.S. trademark on the name IBM. A biographical article in 1940 noted that "This word is on the most conspicuous wall of every room in every IBM building. Each employee carries a THINK notebook in which to record inspirations. The company stationery, matches, scratch pads all bear the inscription, THINK. A monthly magazine called 'Think' is distributed to the employees." THINK remains a part of IBM's corporate culture; it was the inspiration behind naming IBM's successful line of notebook computers, IBM ThinkPad. In 2007, IBM Mid America Employees Federal Credit Union changed its name to Think Mutual Bank. See also IBM and the Holocaust IBM during World War II Jeannette K. Watson Fellowship Thomas J.
