Yahoo CEO Marissa Mayer has lured away one of Google’s top advertising executives to help engineer a turnaround at Yahoo.
Henrique de Castro is leaving Google to become Yahoo’s chief operating officer early next year.
The surprise move announced Monday is Mayer’s highest profile hiring since she left Google Inc. in July to run Yahoo Inc.
By raiding the ranks of her former employer, Mayer risks raising tensions between Yahoo and Google.
The 47-year-old de Castro has been at Google since 2006. He is currently vice president of a major division.
