If you lived in Silicon Valley, Apple had HUGE banners with their Think Different campaign that you could see from 280. I distinctly remember driving around there in 1997, and seeing the banner with Einstein's face, if I remember correctly, and getting goosebumps.
And this was when Apple was a laughingstock at the Brass Ring job fairs (if any of you remember those). I remember no one even bothering to line up for a job for Apple.
I have never lived in California. As to Einstein, the columnist Charles Krauthammer remarked that one common attribute of the notables depicted in the campaign--Einstein, Gandhi, etc.--was that none had ever used a computer, let alone a Mac.
