Of course safe title area is becoming more and more a thing of the past since the flat panel displays now have a fixed spatial dimension. This contrasts with a CRT where the raster size is dependent upon surround sweep circuit stability.
The commercial networks for many years made the HD 16x9 transmission 4x3 safe: that is safe titling was 4x3 protected for legacy 4x3 displays. The last 4x3 displays were sold in about 2005-06 and so I wonder if this is now becoming a thing of the past? (I do not watch much commercial TV these days).
Note that PBS member station broadcast of SD Create and World are now 16x9 and are not produced 4x3 safe. This brings about a new topic which deserves a thread in itself: "How Do You Cope with 16x9 Produced Content on a 4x3 Display?"
