"That idea of URL was the basic clue to the universality of the Web. That was the only thing I insisted upon"

This quote by Tim Berners-Lee speaks to the importance of the URL in the development of the World Wide Web. The URL, or Uniform Resource Locator, is an unique address that determines a specific websites or file on the internet. By developing a universal system of URLs, Berners-Lee was able to make the web available to anyone, regardless of their location or device. This universality was the crucial to the success of the web, and Berners-Lee was determined that the URL system be carried out. Without it, the web would not have been able to reach the level of success it has today. Berners-Lee's insistence on the universality of the URL was an important step in the development of the World Wide Web.
