Adidas supposedly pulled its $10+ million ad campaign from the iAd program because Apple CEO Steve Jobs was being too much of a control freak. According to one industry exec, Adidas decided to cancel its iAds after Apple rejected its creative concept for the third time.
In August it was reported that advertisers are becoming increasingly frustrated at the slow start of the iAd network due to Apple's tight control of the ad-making process. Apple is not allowing companies to develop their own ads yet; rather, it has an internal team that is responsible for producing the creatives.
At the time, Chanel was thought to have pulled their campaign and now it seems Adidas has joined them.
