Musk tapped Yaccarino to replace him as CEO in 2023, shortly after purchasing the platform, then called Twitter, for $44 billion in October 2022. He said Yaccarino would focus primarily on Twitter's business while he focused on product design and new technology.

The CEO of X, Linda Yaccarino, said on Wednesday she would step down from the role in a surprise move, ending her tenure at the Elon Musk-owned social media platform that has faced several controversies and challenges including a mass exodus of advertisers from the site.

Yaccarino, 61, took on the role of CEO in May 2023, just months after Elon Musk purchased the app, formerly known as Twitter, in Oct. 2022. She spent two years in the role, which she took over from Musk, before announcing her decision to step down on Wednesday, July 9.
