Digital marketing traces its roots to the 1990s when the internet became mainstream. Early efforts included email campaigns and banner ads. The 2000s saw the rise of search engines, particularly Google, revolutionizing marketing through SEO and PPC ads. Social media platforms like Facebook and Twitter emerged in the late 2000s, enabling businesses to connect directly with consumers. The 2010s introduced mobile marketing, influencer collaborations, and advanced analytics, making campaigns more targeted and data-driven.
