Elon Musk has announced he’s hired former NBCUniversal advertising boss Linda Yaccarino as the new Twitter chief executive. The erratic billionaire confirmed widespread speculation that Ms Yaccarino would take on the role in a Twitter post on Friday. “Looking forward to working with Linda to transform this platform into X, the everything app,” Mr Musk wrote. Ms Yaccarino will focus on business operations, while Mr Musk will stay on as executive chairman and focus on product design and new technology, he said. Hours earlier, Ms Yaccarino said in a statement she was leaving her role as chairman of global advertising and partnerships at NBCUniversal after more than a decade at the media conglomerate. “It has been an absolute honour to be part of Comcast NBCUniversal and lead the most incredible team,” she said. “We’ve transformed our company and the entire industry.” Ms Yaccarino oversaw the launch of the NBC’s streaming site Peacock. On Thursday, Mr Musk teased the appointment when he announced he had hired a woman to take over the social media platform’s top job from him in six weeks. The appointment, six months after Mr Musk said he would step down as CEO, comes as Twitter faces an exodus of advertisers, service disruptions, and renewed scrutiny from regulators. After purchasing the platform for $44bn last October, Mr Musk has fired around 80 per cent of the workforce, reinstated banned accounts, and allowed hate speech to flourish under the guise of “free speech”.
