I certainly hope iAd stays around. After a very bumpy start it has
stabilized into a very solid platform that serves its intended
goal of providing a native mechanism for making money in free
apps. In fact, the performance of iAd has grown so solid over the
past 6 months or so that I recently dropped all other
advertising platforms from Audiobooks (previously I’ve integrated
with MobClix, Admob, and Adsense).
