P&G has been innovating and marketing products effectively since 1887. Some key aspects of their approach include establishing an early R&D lab, pursuing global expansion aggressively starting in the 1930s, developing breakthrough products in the 1960s, making strategic acquisitions to enter new markets starting in the 1950s, focusing on product design and digital marketing more recently, and maintaining marketing investments even during recessions. P&G's long term success has been driven by relentless innovation, far-sighted acquisitions, deep consumer insights, and adapting proven strategies while incorporating new technologies.
