E.g. a few years ago they bet big on 3D TV. At the time I said "huh?". It was destined to fail. Not just because many people dislike the 3D effect, there were multiple standards, there was a need for special glasses, etc.
No, the real (missing) elephant in the room was content. After all, how many times can you re-watch Avatar? Have there even been 10 "good" 3D movies made to date?
So what does this article end with? It says that Sony is betting big on 4K screens. Once again, the key word is "content". Just how do you get 4K content to people at home? About 10 years ago we were all sold the HDTV story. But look at what's being delivered to homes today. Extreme bit starving; an HD TV channel often uses less than 1/2 of what was envisioned. Why? Because most people don't care and so it's more profitable to deliver two or three mediocre quality programs instead of one high quality program.
Those uncaring consumers will now start paying for 4K content? I don't think so! And even if they wanted it, there isn't enough available bandwidth on the cable systems. So now we need a successor to Blu-ray with even more resolution? Great, now each movie will be available in DVD, Blu-Ray and 4K Blu-Ray versions? Don't forget the collectors editions. Don't forget the inevitable re-releases (e.g. special editions), because the video quality of the first release was total crap.
And without 4K content, today's TVs are already more than good enough. My TV set is capable of far better quality than what comes out of my cable. And the quality of video on demand is no better than what's OTA. Usually worse.
Apparently nobody at Sony has managed to convey to top management the unexpurgated version of "this is a crock of shit, and it stinks".
