Whiteboarding
Whiteboarding is the placement of shared files on an on-screen shared notebook or whiteboard. Videoconferencing and data conferencing software often lets documents as on a physical whiteboard.
With this type of software, several people can work on the image at the same time, each seeing changes the others make in near-real time.
Electronic whiteboarding was included at least as early as 1996 in the CoolTalk tool in Netscape Navigator 3.0.
