During the takeover procedures, Sir Martin Sorrell, the founder of WPP, was described by Ogilvy as an "odious little shit", and he promised to never work again. (Reports softened it to "odious little jerk", and when Martin Sorrell signed his next company report, he followed the signature with the letters OLJ.) Two events followed simultaneously, however: WPP became the largest marketing communications firm in the world, and David Ogilvy was named the company's non-executive chairman (a position he held for three years). Eventually he became a fan of Sorrell. A letter of apology from Ogilvy adorns Sorrell's office, which is said to be the only apology David Ogilvy ever offered in any form during his adult life. Only a year after his derogatory comments about Sorrell, he was quoted as saying, 'When he tried to take over our company, I would liked to have killed him. But it was not legal. I wish I had known him 40 years ago. I like him enormously now.'
