A membership organization devoted to defining DVD standards for read-only, rewritable, write-once, video and audio use. Members participate in working groups to develop new standards. Based in Tokyo, Japan and founded in late 1995 as the DVD Consortium, it was renamed the DVD Forum in 1997. "Minus RW" and "Minus R" are commonly used to refer to the DVD-RW and DVD-R formats of the DVD Forum compared to the DVD+RW Alliance's DVD+RW and DVD+R. For more information, visit www.dvdforum.org.
