Well like soneone else pointed out, 3D isn't anything new at all, it's been around for more than 60 years. People never demanded it ALL THE TIME. When Hollywood felt like giving the public a 3D film, they did it. It's kinda like the McRib of movies, people don't expect to see it on the menu every day.
I can remember them broadcasting 3D movies on TV way back in the 80's, on regular, standard sets. All you had to do was skip on down to the 7/11 and grab some cardboard glasses. That's why I feel like all this hooplah is 100% about money. They aren't filling a public demand, they probably made so much money over the past decade switching everyone over to digital TV's that now that their revenue stream is starting to dry up they figured, "hey why don't we change the industry again, this time we'll switch them over to 3D, but instead of using the technology that can be played on everyone's current sets, we'll use that shutter technology so everyone will have to replace all their new TV's with even more newer ones!"!
The problem is that once they have us all switched over to shutter style 3D TV sets in 10 years, they're going to unleash the sets that don't require glasses on us. They're already working on it, by then it will be polished, and that's when they'll anounce all the stations will be switching from the shutter style, to the new technology because they'll conveniently discover that wearing the shutter style glasses for too long (what did the latest study indicate, that Americans watch like 6 hours of television per day?), they cause seizures. So then we'll all have to swap out our newer new TVs to the newest version.
So I say we just put our foot down now and let them know we only need a major overhaul in the television industry every 25 - 30 years. We started out with black and white, then made the transition over to color during the 70's, then over to digital hi-def in the 2000's, so we're good until around 2030 or so. Then we'll talk about which direction we need to go.
