The US Supreme Court takes up the issue of gay marriage this week, specifically whether or not a federal law defining marriage as a union between a man and a woman is constitutional.

It is called the Defence of Marriage Act, and nearly 300 companies are taking a stand against it, calling it bad for business.

From Google to Goldman Sachs, major companies are on board, signalling a shift in corporate culture.
