Apple has launched magazine ads on the back covers of current issues of Time and The New Yorker that cleverly promote the iPad mini -- by exactly reproducing the issues front cover as it would be seen on the device. Apart from a tiny copyright disclaimer and iPad mini logo, the rest of the back cover is left completely blank, allowing the reader to accurately judge how small the iPad mini is. The ad also features a subtle reminder that the publications can be read digitally through Apple's Newsstand.
