iOS leading in ad share

While the latest reports show that Android continues to make significant headway in terms of global marketshare, this does not translate into ad revenue.  

According to Kevin Bostic, writing in Apple Insider, iOS ad share continues to grow, and Android has actually lost ground. Between May 2012-2013, iOS ad share increased from 59 percent to 64 percent, while Android dropped from 41 percent to 36 percent over the same period.

This is good news for Apple, since higher ad monetization means that developers will be more likely write apps for the iOS platform first.
