There’s still a pretty wide gap between what kinds of additional media readers would like in their ebooks and the ability to display said media. Chief among the reasons: most ebook readers just don’ have the capability. Kindle doesn’t support video, iBooks can’t play audio. (It can bounce you out to a YouTube clip, though.) Which is why so many publishers are still going the app route (Enhanced Editions, the much buzzed-about Alice in Wonderland).
I’m interested to see how they handle this with Sebastian Junger’s War, which will allegedly sport embedded video clips. This seems a natural fit: he’s accrued loads of footage from his documentary on the same subject. I also imagine many readers will want to experience the story in these multiple formats.
Here’s hoping the ereader software updates make this no-brainer possible.
