NBCUniversal has named Mark Marshall as its next chairman of global advertising and partnerships.

Marshall has held the position in an interim capacity since May, when previous chairman Linda Yaccarino left the media company to become the CEO of Twitter, now X.

Marshall has held positions at NBCU for nearly ten years, most recently as president of advertising sales and partnerships under Yaccarino. Yaccarino's exit led to Marshall overseeing the media company’s upfront sales. Marshall closed market negotiations last month, securing commitments from advertisers in line with its 2022 upfront, which the company reported was its highest-grossing ever (specific figures were not disclosed). Marshall will report to Mark Lazarus, chairman of NBCUniversal Media Group.

“Mark stepped into this role on an interim basis at one of the most critical times of year for the ad sales business, and over the past three months he has more than proven himself to be the leader NBCU needs to guide this team into the future,” Lazarus said in a statement.  “Mark’s relationships are second to none, and coupled with his transformative vision, I have no doubt that under his leadership we will continue to reinvent and innovate the sales business while super-serving our clients and partners.” 

Prior to joining NBCU, Marshall served in multiple sales positions for Turner Broadcasting.
