David Ko

Yahoo! wants to make it clear: Mobile remains an integral part of its strategy. In fact, CEO Carol Bartz said in her blog yesterday that she's focused on providing consumers with awesome products - "the kind that get you so excited, you have to tell someone about them. Whether on your desktop, your mobile device, or even your TV."

Speculation about Yahoo's mobile strategy went into overdrive after word got out that Connected Life division head Marco Boerries was leaving the company. Under Boerries' leadership, Yahoo's Connected Life division developed a leadership position in the mobile space.

Now Yahoo has named David Ko, senior vice president at Yahoo! Mobile, as the new global head of the team, responsible for the mobile business, strategy and monetization. Ko has been with Yahoo! for nine years. Before leading the mobile business operations globally, he was managing director for Yahoo! Mobile's Asia Pacific business.

Executive changes at Yahoo! also mean the departure of CFO Blake Jorgensen.
