The series was announced on 10 July 2009, under the working title of "Digital Revolution", to examine the impact the World Wide Web has had on society over its first 20 years. Technology journalist and academic Aleks Krotoski would present. The series was launched with an event at the BBC to mark the twentieth anniversary of the World Wide Web, which saw Tim Berners-Lee (credited with inventing the World Wide Web), Susan Greenfield, Bill Thompson and Chris Anderson discuss the World Wide Web.
World Wide Web
JavaScript is a scripting language that was initially developed in 1995 by Brendan Eich, then of Netscape, for use within web pages. The standardised version is ECMAScript. To make web pages more interactive, some web applications also use JavaScript techniques such as Ajax (asynchronous JavaScript and XML). Client-side script is delivered with the page that can make additional HTTP requests to the server, either in response to user actions such as mouse movements or clicks, or based on elapsed time. The server's responses are used to modify the current page rather than creating a new page with each response, so the server needs only to provide limited, incremental information. Multiple Ajax requests can be handled at the same time, and users can interact with the page while data is retrieved. Web pages may also regularly poll the server to check whether new information is available.
