Marketing has evolved over several stages from 1.0 to 4.0. Marketing 1.0 was product-focused and based on the four Ps. Marketing 2.0 was customer-centric and focused on social media interactions. Marketing 3.0 takes a human-centric approach considering consumers' minds, hearts and spirits. It aims for collaboration and building character. Marketing 4.0 is digital-oriented and leverages trends like the influential digital subcultures of youth, women and netizens.
