World wide web (WWW) has become a primary web across the Internet, which has been widely accepted as an information-sharing platform. Due to the nature of the Internet,i.e. accessing with potential collisions, however, bandwidth bottleneck has become a serious issue of WWW, which significantly restricts the growth of web users. This paper proposes a novel information-sharing mechanism, secondary web, which automatically downloads the information that users need or have subscribed into end users’PCs via a broadcast mechanism. End users can retrieve information based on its content semanteme from their local storage instead of Internet. Therefore, due to the avoidance of the information access collision, the secondary web eliminates the bandwidth bottleneck that the primary web is facing and efficiently filters out information garbage as well. The secondary web is expected to be a new information medium, which has low cost and the ability to support the unlimited growth of users.
