Facebook settled five lawsuits alleging that its advertising systems enabled discrimination in housing, credit and employment ads. For the social network, that's one major legal problem down, several to go, including government investigations in the U.S. and Europe over its data and privacy practices.

As part of that settlement, Facebook says it will overhaul ad targeting for housing, credit and employment ads so they can't be used to discriminate on the basis of race and ethnicity, gender and other legally protected categories in the U.S., including national origin and sexual orientation. The social media company is also paying about $5 million to cover legal fees and other costs.
