I agree wholeheartedly with Amy Gahran - CNN's hologram technology was an unnecessary distraction from their otherwise solid election night coverage.
There may be a time when the addition of a hologram adds value to a two-dimensional television news broadcast. Sometimes it takes a while to discover the strategic application of new technology tools.
I don't know how much time or money CNN spent on this. But it reminds me a bit of companies who get the thinking backwards - they have this cool new tech gadget and they try to find a place to force it in to their existing strategy. It's like they decided to debut it on election night because they knew a lot people were watching, and not because they had a strategic need for a tool like that. I always thought you add things to your newscast to get more viewers, not the other way around. Maybe more people will tune in now that CNN has holograms, but I tend to doubt it.
It's like when a company spends a chunk of money to get into Second Life, without really having a need to do it. Virtual worlds may indeed have strategic applications, but when all you get for the money you spend is an article in a tech publication that says you're now in Second Life, well, you should have bought an ad. Better ROI.
