Apple’s iAd mobile advertising network is what’s (in theory) funding iTunes Radio, so changes to the platform should be of interest to the music industry, including marketers. Yesterday, Apple opened iAd up considerably, allowing anyone with an Apple ID to create an account and start making iAds. “Now, it appears Apple has concluded money in mobile ads comes from a wide net; in short, it’ll look more like Google,” claims AdAge, which also notes that Apple has a new feature for iAds: the ability to run short videos within the ad units. Apple will be hoping that going more self-serve will encourage smaller businesses to adopt iAds – something that could entice more labels to use the platform, who were put off by the initial $1m minimum spend when iAd first launched. This in turn could be good news for iTunes Radio, possibly speeding its global expansion. Caveat: AdAge reports that for now, the expansion of iAd doesn’t cover iTunes Radio, but suggests this won’t be long coming.
