Dentsu Aegis Network has retained the huge Microsoft media assignment after a review that began late last year.
In its latest annual report, Microsoft said it recorded advertising expenses totaling $1.5 billion, $1.6 billion, and $1.9 billion in fiscal years 2017, 2016, and 2015, respectively.
News of the retention was first reported by Adweekearlier today.
Dentsu Aegis has handled the account since 2014. A dedicated unit at Interpublic’s McCann handles creative duties, which were not part of the review.
A Dentsu Aegis rep declined comment, referring queries to Microsoft.
Kathleen Hall, corporate vice president, brand, advertising & research, Microsoft, issued a statement confirming the company's decision: “After completing a review of our global media agencies, we are extending our relationship with Dentsu Aegis.”
