E-marketing began in 1972 with the introduction of electronic mail and has grown significantly since the development of the World Wide Web in the 1990s. It involves promoting and selling products and services over the Internet using various digital methods like search engine marketing, display advertising, email marketing, social media marketing, and video marketing. E-marketing can target consumers, businesses, or both, and allows payment methods like cards, cash, and electronic banking. The future of e-marketing is strong, with global spending projected to grow five-fold to $130 billion by 2020, led by the United States, Britain, and Germany.
