As an industry outsider, I assumed that the 4:3 format was surely 
vaporizing as fast as film.  No one (at least in the USA) watches 
media in 4:3 format any more except for on older cell phones, Home 
Shopping Network, and YouTube content produced with cheap cameras or 
cell phones.  The value is so low I assumed that it would be relegated 
to automatic conversion.

There is continued value to 16/9 since many providers are unwilling to 
transmit content in what appears to be a letterbox format.  They would 
rather crop (or even squish) wider content to fit 16/9.  I assumed 
that wide content would be shot so that it would be easily scaled and 
cropped to 16/9 without "pan & scan".
