AOL has announced that its chief marketing officer for AOL Advertising, Erika Nardini, is leaving the company at the end of the year to “pursue other opportunities”.

After spending the past two years in the role Nardini will be succeeded by Allie Kline, chief marketing officer of AOL’s ad-tech division, who will take over Nardini’s duties in addition to her own.

According to AdAge, in Nardini’s role as CMO she focused on promoting AOL’s programmatic products along with pushing the more brand-friendly ad opportunities on AOL’s owned-and-operated properties such as its “Rising Stars” interactive banner ads and the premium video it pitched at its annual Digital Content NewFronts presentation.

Commenting on the appointment of Kline, Tim Armstrong, chief executive and chairman of AOL said: “Allie Kline has been a driving force in the growth of AOL’s media, advertising and publisher solutions platforms. Allie is an award-winning marketing strategist helping to fundamentally reshape the future of the company.”

Kline said: “AOL has seen a rapid shift to programmatic buying, while our clients are still demanding rich audiences. I have witnessed that first-hand. AOL has provided a clear vision for where the Internet is going and is building for it, from amazing premium and programmatic ad experiences to Emmy award-nominated original video series, and everything in between. I am incredibly excited to continue driving that strategy forward.”

Kline has worked in brand management and marketing strategy for tech-focused organisations for over 20 years. She previously held the role of chief marketing officer for big data and social graph company 33Across where she worked with over 375 Fortune 1000 advertisers and 650,000 global publishers.
