New Twitter CEO Linda Yaccarino: Mask Up or Pack Up.

On Thursday, Twitter CEO Elon Musk said he had appointed someone to take over from him as CEO, and it didn't take long for that person's identity to be confirmed. Less than a day later, Musk confirmed that NBCUniversal's head of ad sales Linda Yaccarino is taking on the job. Yaccarino is expected to start her new role in around six weeks.
