A bookmarking system is provided that includes a user input device and a network server. A person who is viewing a program e.g. watching a network news program on television can bookmark an archived version of that program for future reference. The viewer utilizes the user input device to communicate to the network server the identity of the program of interest. The network server uses the identification information for the program of interest to identify a URL for the archived version of the program. The network server transmits the URL for the archived program to the personal computer of the viewer.

Why it's free to use
- Filed March 5, 1999 and granted October 22, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 5, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 5, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
