The smartest person I ever worked for (by about 50 IQ points) once said to me, "there's no secret to what Goodby does. They take classic advertising forms and up-date them to the 21st Century."
The HP Printer ad in Ad Aged's previous post is exactly that. A 21st-century demonstration.
The commercials here are that HP spot's spiritual forerunner. Take 3:16 and see some brilliant work.
