When the picture gets squished for a ticker or special notice, the closed captions disappear. Why?
Closed captioning is used not only for the deaf (its intended audience), but it has also gotten use by those learning to read, those watching TV in noisy places and, of course, those wanting to watch TV while the other person is sleeping, studying, or doing another activity where quietness is required. In a 525-line NTSC picture, the closed captions are transmitted on line 21. When the picture is squeezed, the captions in line 21 has been destroyed, causing them to disappear from your set. Nick used to practise picture-squeezing to run special text during special promotions, usually as part of the U-Picks (and the shows preceeding it), as well as the Big Help-A-Thon. In 2000, Nick halted this practice and just placed a ticker or text onto the picture; this way, not only is the picture’s shape kept as intended, but line 21 is not altered. Nick still squeezes the picture during the closing credits, though the only captions at that point is the funding notice and the people who captioned
