An essay at the San Francisco Egotist describes technologically-driven changes in advertising. What used to be a process of days or a week is not a process of hours. The shift is not, the author points out, confined to advertising:

“Our technology whizzes along at the velocity of a speeding electron, and our poor overtaxed neurons struggle to keep up. Everything has become a split-second decision. Find something you like. Share it. Have a half-baked thought. Tweet it. Don’t wait. Don’t hesitate. Seize the moment. Keep up. There will be plenty of time to repent later. Oh, and just to cover your ass, don’t forget to stick a smiley on the end just in case you’ve overstepped the mark.”
