Television technology has been changing since its invention. However, within the last decade the technology used on our TVs have changed so rapidly, that we’ve moved from analog, to digital, to HD, to Full HD, to 3D, and now finally to 4K TVs. Keeping that in mind, Sony has just released a 84-inch 4K Bravia KD-84X9005, but the only problem is that we’re missing a lot of content. So other than the London 2012 Olympics your going to find it hard searching for 4K content, because 4K content needs to be filmed with a 4K camera, of course. However, if you wait a couple of years, this whole playground will be changed upside down.
