AdAge, via Business Insider, is reporting that Yahoo! is placing more coordinated emphasis on mobile:

We hear that under Jerry and former mobile boss Marco Boerries, the mobile unit worked more like an isolated startup. Now, under Carol and new mobile boss David Ko, the mobile team is working more closely with product teams as mobile becomes a stronger focal area for Yahoo.

We've been arguing for a version of this for some time. We argued directly to Yahoo! that success in mobile was in some ways a key to "reinvigorating" the Yahoo! brand overall. Yahoo! Mobile is a terrific improvement over Go and its previous mobile experiences. 

Yahoo! Mail has historically been the top mobile destination in the US. However, Opera reported yesterday that Yahoo! fell two places in its list of top 10 US mobile websites. And Google has the lead in mobile search. 

Yahoo! has a more developed mobile advertising business than Google (at this point). And it has carrier relationships around the globe that give it access to north of 800 million users hypothetically.

The company needs to keep paying attention to mobile as a highly strategic initiative at the level of CEO. So it's good that Bartz is involved, assuming the accuracy of the report.
