Most of us closely following the rapid industrial shift from traditional print manufacturing to instant digital distribution are no doubt aware of the iPad’s influence on these unprecedented proceedings. While iBooks is gathering steam as a bona fide market juggernaut, many of the best “e-books” to date have been produced and packaged as more standard App Store offerings.

The best-known of these titles, Al Gore’s award-winning Our Choice app, is the flagship product of a new interactive platform developed by startup Push Pop Press. But now, all of a sudden, the rest of the outfit’s written projects are on indefinite hold.

Why?

It’s quite simple, really: Push Pop’s just been bought by Facebook!

For those privy to the social giant’s Project Spartan, this acquisition might seem like evidence of Facebook’s further desire to challenge Apple’s multiple iOS store model. However, Mark Zuckerberg brand has made it quite clear that it’s not interested in formatting and selling any e-books at all.

Instead, Facebook hopes to use Push Pop’s proprietary, gesture-heavy navigation technology in the reinvention and specific refinement of its own mobile app offerings. In their updated “About” page, the newest Facebook employees stress that

the ideas and technology behind Push Pop Press will be integrated with Facebook, giving people even richer ways to share their stories. With millions of people publishing to Facebook each day, we think it’s going to be a great home for Push Pop Press.

This bit of news could mean that we’ll all have to hold out a little while longer for that oft-rumored Facebook iPad app. But, if Our Choice is any indication of what we can expect at launch, Our Wait will be very much more than well worth it.
