With such television makers as Samsung and Panasonic unveiling flat-screen sets that are capable of displaying 3-D content, the format is widely considered the next leap forward in TV technology.So far, 3-D programming has been about stunts and gimmicks rather than an earnest play to engage viewers on a deeper level. With growing competition from other media, however, it may be time for the television industry to push forward with 3-D.
The technological advances are the necessary foundation that network programmers need before they invest more in 3-D.
As consumers invest in televisions that can handle 3-D content -- either over-the-air or through Blu-ray players -- networks in turn will have an incentive to invest in both producing and broadcasting content in 3-D.

Industry experts say that if 3DTV is to be more than a niche market then it needs to be accomplished without the use of special glasses that the viewer must use. The problem is that presently, many of the implementations require the use of glasses for one reason or another. One glasses-based implementation used in movie theaters is that there are actually two overlapping projections on the screen, polarized at 90 degrees to each other. Then, each lens in the glasses has its own polarizer at 90 degrees so that each eye can only see what it is supposed to. The advantage is that it's a completely passive system meaning cheaper glasses and no headaches.
