Yaccarino will focus on business operations, Musk tweeted, while he will oversee product design and new technology. The duo will “transform this platform into X, the everything app,” he said. (The Logic)

Talking point: Yaccarino, who has yet to tweet the news herself, will start in about six weeks. She has been with NBCUniversal Media for more than 11 years, most recently as chair of global advertising and partnerships, according to her LinkedIn profile. She led a 2,000-person team that has generated more than US$100 billion in ad sales since 2011, according to a cached version of NBCUniversal’s website. Her experience may signal a shift at Twitter, after Musk’s takeover saw advertisers flee the platform as he laid off thousands of staff. Ad revenue has since slowly been recovering. Some who favour Musk’s approach to free speech have speculated Yaccarino could attempt to revert some of his initiatives, pointing to her work with the World Economic Forum.
