Tinman and I talked about this last year. Marc was the go to guy for studio monitor color calibration and repair, and in the mobile trucks they are indeed going away from CRT, but mainly due to weight.
People like JVC are charging a small fortune for digitals, and guess what, they are breaking down more than CRT according to Marc.
Heck, the article is nothing new, CRT is a dying breed, and one thing the studios can't have is unreliable monitors, so the change was inevitable.
Saying CRTs are power hungry though is false. Marc told me that some properly calibrated plasmas are more efficient than CRT, and for the size of image, I'd say most digitals aren't any more energy efficient than CRTs ever were.

When was the last time you saw a CRT TV on the shelf at BB?
Even if it is better, what's the point of mastering on a NA product for a NA product? You know what they say. When in Rome....

I am sure most of you have done this but I am always amazed at the amount of heat generated at a bunch of Plasma TVs when then are displayed by large chain stores.

I can feel the heat on my face from the *panel* of my 30" HP IPS LCD. It's quite uncomfortable to touch. The 24" Dell IPS next to it is bad, too, but not quite as; the 24" Samsung TN on the other side is a lot cooler.
As far as colors go, IPS panels are a world different than TN; if you haven't seen a good, calibrated IPS panel it's not fair to judge them vs. CRT. The only problem I have with this one is a -very- slight amount of color shift, and a tiny 'sparkly' feel to whites. Aside from that, it's gorgeous.

This all started when Sony cancelled its RoHS compliant BVMs, and decided to stop making them all together. This was 2005... Leaving people hanging as the LCD replacement (first not good enough to some) didn't become available for another 2-3 years.
JVC basicall was left to hold down the fort, and JVC only supplied small (20" 4:3) monitors. The local pay-tv company bought those for its ingest suites.
Production monitors and small editing monitors have been thrown out years ago, bigger reference monitors have been saved moved from less critical to colour critical applications, and have been awaiting death since. And yes there has been a lot of discussion on how to evaluate broadcast material, and what the new reference should be as a diverse population of new targetdisplays have flood homes.
Just read the article, and basically it says the same as I wrote above. Charles Poynton is one of THE gurus in the field, so these are familliar points;-).

Yes, he his! From his website:
| Quote: | Charles Poynton – square pixels and 1080
It was 20 years ago today (approximately) that I launched the effort – ultimately successful – to establish square sampling (“square pixels”) as the standard for HDTV. I am the inventor of the number 1080 found in HDTV standards. My efforts resulted in my being awarded SMPTE’s David Sarnoff Gold Medal. See the entries toward the bottom of my Video Engineering page. |
If ever I have the chance, I'd like to personally shake that man's hand. As a content creator who used to work with video a lot in the late 90's, non-square pixels was one of the most obnoxious things about the medium. I HATED that. I don't do a lot of video anymore anymore, but I did just finish a small HD project recently, and ho...lee... crap it was nice to work with square pixels and not have to do any conversion or aspect ratio correction. Working in 1080p/24 and not concerning myself with interlacing was super-nice, too!

He generally does presentations at NAB/IBC. Never met the pink haired (well at his wedding a few years back where he and his bride had matching streaks in their hairdo's) one. Craig Birkmaier was detailing this past week how he and his fellow workinggroup members thought they had the ATSC standard worked out and settled, eliminating interlace and non-square samples, to return and see the grand alliance politics had worked those bases of IP revenue back in. 1080 vertical samples made the NHK Hi-Vision system square as it already had 1920 horizontal samples, but only 1035 active vertical samples. The Vision 1250 system had 1125, so 1080 was smack down in the middle.
