A lot of commercials are CCed, and most of the ones that aren't are  
local ones, not national or regional.

At the very least a commercial should issue a "clear" at the start,  
even if it is not captioned, or you can have all sorts of hilarious  
situations where the last line from the preceding program/commercial  
is left hanging.

But it is not consistent enough to be very reliable as far as  
commercial detection.
