I’ve created a page on my new wiki with a description of some of the most used terms people use when referring to cross-media. I’ve tried to explain how they relate and when they don’t. It is not a comprehensive list of all the terms and their meanings. It is also not my personal list of terms I use in cross-media design. But I think it helps demystify some contradictory uses of the big ones, like “convergence” [deep echoing voice].
Let me know of any terms and usages you know and where I explained things incorrectly!
