Some of 21st Century Fox’s best-known ad-sales executives will leave the company when it closes a large sale of its assets to Walt Disney and streamlines itself into a company known currently as “New Fox” in 2019. The ad unit will be under Marianne Gambelli, a veteran who once led ad sales at NBC, who has been named president of ad sales for the “new” Fox, and will oversee efforts for units like Fox Sports, Fox News Channel, Fox Business Network and Fox Broadcasting that will remain after the $71.3 billion deal closes next year.
