While working at CERN, Tim Berners-Lee saw the need to share scientific data efficiently. Early attempts were met with skepticism, and colleagues doubted the practicality of linking documents across networks. Berners-Lee persisted, creating the first web server, HTML, and browser. The turning point came when the web was made publicly accessible in 1991, revolutionizing global communication. His story shows that vision combined with simplicity can spark a technology that transforms the world.
