You've probably heard of me say it so many times "Safe Areas!!!"
The reason I do this is let people know about keeping their important info on graphics in a overscan safe zone:

This is what overscan can do:

Notice the graphics are not in the safe area especially the ticker.
Overscan can be a good/bad thing, the whole point of it is to crop the black bars and additional information like data lines to keep the TV set full at all times, but too much can be a nuisance.

Without a safe area guide it would give the impression of a normal image rather than a TV mock, it just looks tidier and organised. The more important thing is the design and you can incorporate the safe area into it later.
