World and 24 are digital so to be truly anorakky - Black is 16, White is 220 (in 8 bit digital video...)
<Anorak mode off>
Sorry to be so sad... And yes - How were World able to run with such crushed cameras, yet with such a sat-up plasma for so long. (The camera shots had no detail in the blacks, yet the blacks in the plasma were nearer a bright grey!)

A video image is made up of varying levels of volts. Black is 0v (0%), white is 0.7v (100%).
It is standard practise throughout the TV industry to have black set at 5% so the viewer is guaranteed to see all the detail.
World 'crush' their blacks, so some detail is lost. If it were possible, their blacks would be minus volts.
However, saying that, crushing the blacks gives the illusion of cleaner & sharper images. Try it yourself on your TV... increase your brightness & contrast controls - don't you think the picture looks soft by doing that?
Now decrease the brightness - doesn't it look sharper?
