I guess the main point is whether or not all of these broadcasters and/or tv manufacturers have done safety studies of the effects of 3D 'all the time' in our lives verses just during a 2-3 hour movie every once in a while. I could definitely see people (in these companies) dismissing there being a problem just because "people go to 3D movies all the time" even though the 'amount of exposure' is orders of magnitude different.

> I am a bit sensitive about this general issue (nothing to do with 3d) as there have been quite a few deaths in my area in the last year due to people's fears of radiation from mobile phone towers (which are in fact no where near their house, but that is another issue).

I'm not advocating that kind of crazy. I'm just saying that it would be entirely irresponsible for companies to push this technology without any sort of testing. In general, I would be mostly concerned with children. I don't want to bring out the 'think of the children' argument here, but children have developing brains, and if this could adversely affect their brain development there should be a bold warning label at the very least. (Or such broadcasts should just be 'few and far between' -- i.e. only some 3D movies on TV or a 3D channel or ability to switch between 3D version and 2D version -- so as not to force children/parents into the 'consume potentially harmful content or consume no content at all' decision)

On the flip-side of your argument, I think that entirely too many companies rush products to market before bothering to ponder any sort of implications (though this is mostly just a problem with food/medical products, but things like infant-/baby-oriented products have this issue too).
