2000 - Groove pushes sharing ideas on the Net - a new advantage over Drupal

Groove Networks takes the wraps off software for collaborating over the Internet. Groove brings together a number of disparate computing concepts that have been floating around the Internet for years, such as home and corporate video conferencing, the exchange of music, video and photo files, and instant messaging and chat, among other things. But rather than making consumers and businesses use several different products for these activities, Groove has bundled the functions into a single product. Groove will also sell the product to individuals and consumers. The company envisions families sharing gossip, photos, music and other information despite being separated by long distances. The software creates a shared space on a computer for files that can be shared with other people using Groove over a corporate network or across the Internet. Napster takes a similar approach to sharing music files, which are stored on individuals' PCs but accessed through the company's software connecting through a central server.
