wow. fascinating. the one thing that is a bit absent from this discussion is the wave of video that is about to sweep over the internet over the next 1,2,3 years.
That is going to drive positive change for .tv. See what Budweiser is doing with Bud.tv ($30M investment in 2007) and Demand Media with the Registry as a whole.
So while their pasts might have both been pretty quiet, I can't see what comparable event could get CC to start moving into mainstream acceptance.
I will note that my portfolio is weighted highly toward .tv so perhaps I am badly biased so you can take my comments in that context, BUT, I have had a lot of conversations with non-domainers about .tv and got very quick understanding from them TV is a logical place for video assets.
I think those discussions would be a lot harder explain why .CC and not .net, .biz, .info, .ws, etc.
