Now in the late 90s were TVs sold in 4:3 or 14:9 aspect ratio?
The first 16:9 CRT TVs started going on sale in Europe in the mid-90s - before DVD and DVB 16:9 full-height sources became available. They were initially sold to display letterboxed VHS and Laserdisc movies full-screen. Sony launched a PlayStation 16"(?) 16:9 CRT portable TV which was very popular as a floor monitor in TV studios (the only other options were 4:3 CRTs running scan-crushed letterbox)
14:9 was never a broadcast aspect ratio (it was just an active area within a 4:3 or 16:9 frame - we used 14L12 and 14P16) and no 14:9 TVs were sold AFAIK - as there was no real point to them.
14L12 was the 14:9 letterbox that we showed most 16:9 shows in on 4:3 outlets.
14P16 was the 14:9 pillars that we used to convert 4:3 news content (and other archive) for shows made otherwise in 16:9 for 16:9 outlets.
I never understood the point of 14:9. I can understand the argument of viewers being put off by heavy black bars - but surely they would have gotten used to them after a while?
It seems strange now - but in the 80s and early 90s when the largest TV most people had was a 24" 4:3 CRT, a 16:9 letterboxed image was really quite small. It wasn't a case of getting used to it per se - more that people weren't happy with having such a smaller picture.
It's really amazing to think we've (i.e. my household) gone from 21" 4:3 CRTs to 50" 16:9 flat panels in 25 years...
All the broadcasters got LOTS of complaints when they showed letterboxed movies. LOTS of complaints.
The BBC therefore trialled a weekend of 14:9 letterbox - as they knew 16:9 letterbox wasn't an option, and felt 4:3 centre-cut was too limiting creatively. The weekend's shows were shot 4:3 but masked with black bars top and bottom I believe (camera operators framing appropriately). Far fewer complaints were received (I suspect CRT overscan reduced the bars yet further) and that set the option.
The exception to the 14:9 rule was sport - 4:3 broadcasts of 16:9 sport were 4:3 CCO (letterboxing sport caused the most complaints I believe...)
