If you're asking, "Can you use CC to indicate whether you're in a
commercial or not?", I'd sadly have to say, "no." I've seen some
ads w/CC, and plenty of programs w/o CC. (This is North American
SDTV broadcasts, both digital cable and (when it existed) analog
cable.) Occasionally the formatting changes dramatically, but again,
you can't tell a priori whether it's the programming or the advertising
that has either double-spaced captions, or captions in all caps vs
mixed case, etc.
