Apple's annual developer conference in San Francisco.
Apple Continues 'Designed by Apple' Campaign With Double-Page Print Ad
The text in the ad is identical to that used on Apple's website for the campaign.
Along with this new print ad, Apple has been running the new 60-second 'Our Signature' spot in a wide television campaign, and it's been reported that other ads in the campaign will be following in the coming months.
Update: Apple's "Designed by Apple" feature page contains four different background images, and it appears that Apple is indeed running corresponding print ads in various newspapers, with a different version appearing in the Chicago Tribune.
