That's actually really interesting about all ads being public like that! Didn't know that. Is it because of some regulatory requirement or just because it's useful business wise?

(anyway many of the coca cola ads you linked have some theme of togetherness and community, which can be said to prey on people's insecurities around being lonely. Drink this sugar+caffeine solution and you'll be less lonely. Yes you start to sound like a paranoid schizophrenic when analyzing ads like that but that is how it works.)
