With NTSC it used to be that consumers really hated the black bars
simply because TV's were so small you could not afford the wasted space
and still get enough detail out of SD on a small TV to see the damn
picture. But now large HD displays are becoming cheaper and much much
more common and horizontal or vertical black bars do not really cause
that problem.
Meanwhile CRT's are going away and most displays no longer have the burn
in problem that used to be the other reason to avoid the bars.
So generally I don't think it is as important to fill up the screen
anymore. Again, I prefer the bars and keeping very close to the
original image.
