Linda Yaccarino is a potential candidate to replace Elon Musk as the CEO of Twitter, according to a WSJ report. She is currently the Chairman of Global Advertising and Partnerships at NBC Universal, where she has been for over a decade. Yaccarino has played a significant role in the development of NBC Universal's ad-supported streaming service, Peacock, and has expertise in e-commerce and operations. She is also the Chairman of the World Economic Forum's Taskforce on Future of Work and sits on the WEF's Media, Entertainment, and Culture Industry Governors Steering Committee. Yaccarino's experience in advertising could potentially help Twitter overcome its slump in ad revenue. It's worth noting that this information is based on a hypothetical scenario presented in a slide presentation by Danny Cyril Dcruze, and the actual outcome may be different.
