As advertisers use augmented reality to enrich their ads, publishers use it to add to their content. First was Red Bull with the October issue of Red Bulletin.
The new Esquire (December issue that just came out) also has AR all over it. Watch the movie for an introduction.
The Financial Times had AR some time ago. But that was just an Ad Hoc thing. It had an article on AR and illustrated it with some of its own.

It all feels a bit gimmicky for the moment, what the magazines and newspapers are doing. But given the situation this industry is in, it is time for experiments and trying out new things to find new revenue streams or new ways to add value.
