But “Dear Sophie” is more of a classic form of Madison Avenue pitching. It’s probably something that Don Draper would come up with if Larry and Sergey were his clients.

They would tell him that their product, the Chrome browser, has a lot going for it over its competitors, like speedier response and a single box to type in addresses and search queries. It runs web applications more efficiently than other browsers, they’d tell him, and if everyone used it, it would hasten a new paradigm of cloud apps. Draper would say that all that stuff is well and good. But for our commercial, we’re going to show a tear-jerking evocation of a father compiling an online scrapbook for to his daughter as she grows up.

Straight out of the Kodak playbook — don’t brag about your specs, but play that song “Where Are You Going My Little One,” and out will come the handkerchiefs. It’s also a stratagem used by banks and insurance companies.

And now Google does it.
