According to Harvard Business School professor David Yoffie, Apple has generated a scant $400 million in free iPhone advertising since its announcement (granted, at least $200 million of that was from Gizmodo alone). He explained:
No other company has ever received that kind of attention for a product launch...It's unprecedentedI doubt that the iPhone announcement drew society's attention more than, say, RCA's first color television or Phillips' first VCR. But given the greater size and spread of media today, I guess that "unprecedented" is still no exaggeration.
