As the Internet revolution reshapes the world, its usage across the globe reveals a glaring digital divide between developed and developing nations. This paper explores why the Stratification model of Internet diffusion exists, highlighting critical obstacles like prohibitive costs, inadequate infrastructure, language barriers, low education levels, and a lack of relevant content for underserved populations. Using diffusion theory, the study emphasises the Internet's unique challenges compared to past innovations like television or radio, arguing that these deep-rooted barriers maintain inequality. Offering a request for further research and policy-driven solutions, the paper examines the urgent need to challenge the global digital divide in the 21st century.
