Amazon.com Inc. announced this week that it will require women and people of color to be included in the pool of applicants for its board member positions. The policy is being implemented at the Seattle-based behemoth in spite of current board members’ initial opposition, according to a report from Recode.

But Amazon is not the first major company to adopt the so-called Rooney Rule. It was first established by the National Football League in 2003 to increase the number of ethnic minorities in head coach and senior football operations positions. Since then, some in corporate America have embraced the policy as a means of boosting hiring diversity, including several tech companies.
