But iAd might have another effect: driving up ad pricing double to triple current rates. That might be welcome for ad sellers, but not for buyers.
Since Apple never likes anything but the "premium" position in any market where it competes, that might not be too surprising.
According contentSutra, iAd cost per thousand impressions will be highly variable in terms of cost, but in some cases could wind up being triple what marketers are used to paying for banners, and double the price of a video ad on mobile (click on the image for a larger view).
In other cases, a very successful campaign that generates an unusual number of clicks could wind up being more than seven times what an advertiser had anticipated.
Keep in mind that Apple is setting the minimum annual spend at $1 million for brands to use its iAd platform. To put that in perspective, consider that Jaguar and Land Rover in 2009 spent about $1.6 million in aggregate for mobile marketing.
Some advertisers might decide they like the iAd formats, and start shifting lots more money into mobile advertising. Others will push back against the price and take a wait-and-see attitude. Either way, iAd is going to have complex impact. It likely will spur larger mobile advertising commitments from some buyers more concerned with cutting edge than return on investment. Most will watch and see what happens, at least in terms of the high-end, showcase content Apple wants to show it can produce.
