Elon Musk appointed Linda Yaccarino as chief executive of Twitter, five months after he said he would relinquish the role. Mr Musk took over the company last October. Ms Yaccarino comes from NBCUniversal, where she was in charge of advertising. Mr Musk said his new hire will focus on day-to-day operations while he concentrates on product development, as he strives to “transform this platform into X, the everything app”.
