Twitter has hired Marjorie Scardino as their first female director. Scardino is the former Pearson PLC CEO. This past year, Twitter has been highly criticized for not having a female as board director. “@twitter Thank you. There couldn’t be a more exciting time in Twitter’s history to join!” wrote Scardino in a tweet. Scardino was also the CEO of The Economist Group. She will be replacing David Rosenblatt on the board’s audit committee.
