I want to know the answer to the following question:
In 1961 IBM's nondiscrimination policy was expanded to include what?
All the background I'm provided with is that "In 1952, Thomas J. Watson, Jr., published the company's first written equal opportunity policy letter, one year before the U.S. Supreme Court decision in Brown vs. Board of Education and 11 years before the Civil Rights Act of 1964.". Is that enough to answer the question?
