Oreo cookies are an American icon. The product was introduced in 1912 by the National Biscuit company (Nabisco). Today annual sales worldwide exceed $40 billion. Oreos continued to be a Nabisco product until the merger which created RJR Nabisco in 1985. Three years later came the KKR takeover of RJR Nabisco. In 2000 the cookie division was sold to another tobacco company, Philip Morris, and incorporated into that company’s Kraft subsidiary. In 2007 Philip Morris (now renamed Altria) divested Kraft, and in 2012 Kraft in turn divested the division which bakes Oreos into a new company, Mondelez. The biscuit filling has undergone minor changes and the top pattern has been redesigned, but otherwise America’s favourite cookie has evolved little over the century. Only the ownership of the brand has changed. Repeatedly. ‘What did it have to do with doing business?’, Bryan Burrough and John Helyar asked in the final sentence of their study of the KKR transaction, referring to the changes in corporate structure. It is an appropriate note on which to end this chapter.
