(Reuters) - Elon Musk has named former NBCUniversal advertising chief Linda Yaccarino as Twitter's new CEO, as the company tries to reverse a plunge in ad revenue.

Yaccarino will take over a social media platform beset with challenges and a heavy debt load, after she spent several years modernizing the advertising business at NBCUniversal, which is owned by Comcast Corp.
