Whiteboard
Albert Stallion invented whiteboards while working at Alliance in the 1960s. Alliance (now known as PolyVision) produced enameled steel for architectural cladding, but Stallion noted it could also potentially be used as a writing surface. Stallion later left Alliance to form his own whiteboard production company, MagiBoards.
WorldWideWhiteboard
The WorldWideWhiteboard product was apparently the first successful web collaboration tool in wide use in education. Online whiteboards generally can accommodate a theoretically unlimited number of participants and an instructor in a synchronous, i.e., live interactive session. The WorldWideWhiteboard allows for both audio and up to four video streams, as well as numerous asynchronous modes of interaction.Certain of these studies have been cited widely, mainly because of the seminal role of the WorldWideWhiteboard as an educational Web-conferencing tool. (See, for instance, Reushle and Loch in "Conducting a Trial Web Conferencing Software." and the Abraham Baldwin Agricultural College Quality Enhancement Plan for 2007)
