Flexplay

Flexplay is a trademark for a discontinued DVD-compatible optical video disc format with a time-limited (usually 48-hour) playback. They are often described as "self-destructing", although the disc merely turns black or dark red and does not physically disintegrate. The technology launched in August 2003 as a joint-venture with Disney's Buena Vista Home Entertainment under the name eZ-D. The Flexplay concept was invented by two professors, Yannis Bakos and Erik Brynjolfsson, who founded Flexplay Technologies in 1999. The technology was developed by Flexplay Technologies and General Electric.
