David Rosenblatt Out, Henrique De Castro In as Head of Google's Display Ad Efforts

Google has named Henrique De Castro to spearhead its display ad ambitions as managing director, global display and YouTube advertising. He will replace David Rosenblatt, the former chief executive officer at DoubleClick, who will leave the company next month, Google has confirmed.

Based in London, De Castro is currently managing director European sales for YouTube & media platforms. He joined Google in 2006 from Dell, prior to which he worked for McKinsey & Company. Rosenblatt’s departure was first reported this morning in The New York Times.

Rosenblatt sent an e-mail to colleagues and family members explaining he would depart the company on May 15, the report said. A founding employee at DoubleClick, Rosenblatt led the company’s technology, data and research groups before becoming president and then CEO. His current title is president of global display advertising.

He’s the latest in a string of senior execs to walk out on Google in recent weeks. Others have included Tim Armstrong, president for the Americas, who became AOL’s CEO last month; and Sukhinder Singh Cassidy, president of Google’s Asia-Pacific and Latin America, joined venture capital firm Accel Partners.

Before joining DoubleClick in 1997, Rosenblatt worked for S.G. Warburg & Co, in Hong Kong, London and New York, advising clients on mergers and other financial and strategic transactions.
