Background

PlanetAll was possibly the first social networking site on the Internet. The site had more than 100,000 groups, organized around real-world counterparts such as academic institutions and employers. When the user entered the name of his or her university, the service would list the user's classmates who were also members of the service. Users could exchange authorization to access the each others' contacts. Many sites at the time offered web-based address books and calendars, but PlanetAll.com combined the two: when a user entered travel plans into the calendar, the service would cross-reference the destination with the address book, as well as the user's contacts' travel plans; the site would then notify users when they would cross paths with their contacts.

 said, "PlanetAll is the most innovative use of the Internet I've seen. It's simply a breakthrough in doing something as fundamental and important as staying in touch. The reason PlanetAll has over 1.5 million members—and is growing even faster than the Internet—is simple: it creates extraordinary value for its users. I believe PlanetAll will prove to be one of the most important online applications."

Less than two years later, Amazon.com shut down PlanetAll.com. On July 2, 2000, they told PlanetAll members, "We are pleased to announce that we have completed the integration of the key e-commerce related features of PlanetAll.com into our main site at Amazon.com... Although PlanetAll.com will be going away, you'll still be able to enjoy some of the tools that help you keep in touch with like-minded folks."

Amazon's "Purchase Circles" feature was based on PlanetAll, and some of PlanetAll code was used to improve Amazon's Friends and Favorites area. The only calendar feature that appears to have remained, however, is the date reminder. Amazon spokeswoman Patty Smith said after Amazon had absorbed the technology, it did not see the need to maintain PlanetAll. "It seemed really superfluous to have it running beside Friends and Favorites," she said.

Many of the 1.5 million members were upset by the loss of the utility; one internet journalist wrote later that year that she was "in mourning" for the service.

A networked computer system provides various services for assisting users in locating, and establishing contact relationships with, other users. For example, in one embodiment, users can identify other users based on their affiliations with particular schools or other organizations. The system also provides a mechanism for a user to selectively establish contact relationships or connections with other users, and to grant permissions for such other users to view personal information of the user.
