Measurement firm Comscore has appointed Jackelyn Keller as chief marketing officer.

Keller succeeds Tania Yukia, who left in 2023 after helping reposition the brand around the future of media measurement.

The new CMO brings extensive experience in linear TV, streaming, digital and programmatic advertising, as well as product marketing and revenue strategy.

She previously served as global head of product marketing at demand-side platform (DSP) Quantcast. Prior to that, she was head of market intelligence and global product strategy at Samsung Ads, where she helped launch Samsung’s DSP.

“[Keller’s] background in operations, product, and revenue strategy, paired with her exceptional talent for positioning and creating accessible branding, exemplifies our unwavering commitment to empowering our clients in this rapidly evolving media landscape,” said Jon Carpenter, Comscore chief executive officer, in a statement.

Keller has been advising Comscore’s leadership team on positioning, creative strategy, and marketing efforts since September. She has also facilitated new initiatives, including Comscore Data Divas and Barbershop, Beauty and Local Buzz, which will kick off at CES in next week.

At Comscore, Keller is looking forward to “writing the measurement playbook for streaming, local, and national measurement,” she said.

Back in October, Comscore renewed its partnership with VIZIO’s Inscape, allowing the company to continue incorporating smart TV viewership data into its measurement and ratings offerings.
