Ok Ramon, but globally it wouldn't make sense, your idea of
fingerprinting the thousand and thousands of advertisements just in the
USA alone would add up to be a huge amount.

Are you sure that add breaks aren't 'cut' the same on a global basis? it
would then make sense in that globally the advertisement 'pre-cursor'
and 'post-cursor' would most likely be the same
