Ten years ago next month, IBM Corp. moved its global account to Ogilvy & Mather
without a review, summarily firing more than 40 agencies. "Ogilvy & Mather will help us deliver clear, consistent messagesand in the most efficient way possible," vowed Abby Kohnstamm, then and now IBM's marketing chief. IBM got it right. From "Solutions for a small planet" to "e-business on demand," Ogilvy's work brought back a fallen brand and redefined technology advertising.
