Neil McElroy wrote a three-page memo in 1931. He was a junior marketing executive at Procter & Gamble, frustrated that Camay soap received less internal attention than Ivory. His proposed solution — a dedicated manager responsible for a single brand's marketing, budget, and competitive strategy — became the organizational template that Unilever, Nestlé, Colgate, and every major consumer goods company subsequently adopted as standard operating structure. P&G did not invent detergent or soap or shampoo. It invented the way those products are managed. One hundred eighty-seven years after William Procter and James Gamble founded their candle and soap partnership in Cincinnati with roughly $7,192 in combined capital, the company generates $84.0 billion in annual revenue across more than 180 countries under brand names that occupy the mental shortcut position in categories their consumers never reconsider: Tide for laundry, Pampers for diapers, Gillette for razors, Head & Shoulders for dandruff. That mental shortcut — the automatic reach — is the business. Everything else is infrastructure supporting it. The 2014-2016 portfolio restructuring divested more than 100 brands, including Duracell to Berkshire Hathaway, Iams and Eukanuba to Mars, Cover Girl and Max Factor to Coty. What remained was approximately 65 brands where P&G held the number one or number two global market position. Jon Moeller, CEO since 2021, inherited a concentrated, high-quality portfolio and has driven it toward pricing power and volume growth in the years since. The $57 billion acquisition of Gillette in 2005 was the largest in P&G's history — and remains one of the most analyzed case studies in DTC disruption, as Gillette's U.S. Market share has declined from roughly 70% to approximately 50-55% since then. That decline did not happen because of inferior razors. It happened because Dollar Shave Club and Harry's demonstrated that subscription delivery and direct consumer relationships could erode brand premiums that had seemed permanent.
