Due to the cost, Carter said he's mainly sampled free 3-D movie trailers provided on-demand by his cable TV company. A trailer for the latest "Transformers" movie didn't make him more enthused. "One of the robots pops out at you, and it felt forced." ''It's not consistent," he said, noting that 3-D effects aren't noticeable much of the time. He said he's not knocking the technology, he's just disappointed with the way it's being used.
Nowadays, 3-D is just one feature on TVs with bigger screens. It is usually grouped with other upgrades that include motion-smoothing technology and light-emitting diodes that are smaller, more energy efficient and display color contrast better than traditional liquid crystal display sets. It's difficult to isolate how much 3-D adds to the price tag of an individual set because of this bundling, but according to IHS the average 42-inch set with 3-D is about $200 more than a similar-sized one without. Some 3-D TVs, however, can be found for cheaper than others of the same size.
"There's very little direct consumer demand," said Tom Morrod, a TV technology analyst with IHS in London. Some consumers buy TVs which happen to have 3-D, but they don't bother to get the glasses needed to watch them, he said.
"They don't see a value with it. Consumers associate value right now with screen size and very few other features."
Sluggish demand for 3-D on TV has caused programmers to hit pause on rolling out new shows and channels.
In June, DirecTV turned its 24-hour channel, n3D, into a part-time network that only shows special event programming like the Olympics, in part to avoid the heavy use of reruns caused by a lack of new material. Last year, AT&T dropped ESPN 3D from its lineup, saying the $10 per month cost to subscribers wasn't justified given low demand.
So far, ESPN 3D is the most aggressive network in terms of shooting original 3-D productions. It has about 140 per year. It also has the widest distribution, according to research firm SNL Kagan, no doubt because popular sports network ESPN includes it in negotiations with distributors. Though few own the hardware to watch the channel, ESPN 3D now pipes into 60 million U.S. homes.
Without extra subscriber fees, it could be difficult to make a big business out of 3-D production, especially because it's more expensive than 2-D. Every 3-D camera set-up requires two cameras. They have to be mounted on a special computerized rig that aligns them. And someone in a back room has to adjust a knob that determines how cross-eyed the lenses are. That can require twice the manpower for the same camera position, boosting costs when revenues aren't going up very much.
Advertising, the other pillar of the TV channel business, is also hampered because of the lack of audience data.
That has resulted in an odd arrangement. Companies that run advertisements on ESPN 3D, like movie studios, actually have their ads played a second time in 2-D on ESPN and other channels so they can meet their goal of reaching a measurable number of people, Burns said. That uses up 2-D commercial airtime that might have been sold to other customers.
While he wouldn't say if it's profitable, Burns said ESPN 3D is still a revenue-generating business that is "doing well," because of how the network accounts for revenue from distributors and advertisers.
3-D TV is not a complete bust. Burns and others expect that as more TVs are sold with the capability, the more viewership will grow, just like it did for high-definition sets and programs a few years ago.
"It took five years before reporting systems caught up and we knew who actually had the service," Burns said of the launch of HD. "It's not unfamiliar territory to us. We've been down this road before."
For TV signal providers, carrying 3-D channels before they really become mainstream wins them points with their savviest technophile customers, the kind who jumped on the HD bandwagon early —a decade ago.
In many ways, though, the comparison to HD isn't a good one.
Watching 3-D is a problem for about 6 percent of Americans with certain eye problems, according to Dr. David Maino, a professor with the Illinois College of Optometry. They simply can't see in 3-D or suffer dizziness or nausea when watching.
