What probably originated as a light bit of corporate comedy -- Logomotto, a witty mashup of one company's logo with other companies' slogans, by the brilliant minds at Google Blogoscoped -- actually has a surprising side effect: exposing the frightening reach of advertising in our over-marketed age. Sure, the combinations are often hilarious (on my first try, I got the Domino's Pizza logo with Sprint's "Can You Hear Me Now?" tag, which felt like every pizza-delivery phone call I've ever placed). But when you realize how these phrases have entered our psyches and resonate with test-market perfection, it gets a big scary. McDonalds+Nike? Just Do It.
