By Saundra Latham, Editor at LinkedIn News –– It’s official: Twitter has a new CEO. Linda Yaccarino, head of global advertising and partnerships at NBCUniversal, will take over the top job from Elon Musk, who acquired Twitter in October for $44 billion. Musk confirmed Yaccarino’s hiring Friday, saying she will “focus primarily on business operations, while I focus on product design and new technology.” Musk said Thursday that he will transition to new roles as executive chair and chief technology officer.

Yaccarino had been at NBCU for over a decade and was instrumental in launching the Peacock streaming service. Musk says Yaccarino will help “transform this platform into X, the everything app.” He recently merged Twitter into a firm called “X Corp.” and has said he wants to build an all-in-one app similar to China’s WeChat.
