Interactive Print - Augmented Reality
Sure, electronic editions have their advantages. I've never heard of a Nook edition getting caught in the U.S. Postal Service's FSS (Flats Shredding System) or having out-of-register ads. You can embed sound or video, track click-throughs, count how many people saw an article or ad, and do all kinds of other tricks that would make Gutenberg's head spin.
Engaging with animation and Augmented Reality will lend itself to instant opt-in for contests, redirects to e-commerce, exploratory views of products, or even crossword puzzles without using a pen. This is another area where offline will merge with online and we can then make more direct comparisons of metrics for each tactic or campaign. At the same time, it will also represent a new world of standards, formats, best practices and everything else we've come to expect with true emerging media.
