"This DVD will self destruct in 8 hours." No really. Get this. "Once the packaging is opened, the disc will work for only eight hours before being made unreadable by a dye sandwiched between the DVD's layers that interacts with air, leaving it opaque." This will be tested by Nappy Roots, a hip-hop group that sounds like every other hip-hop group out there for the past 7 years. Brilliant comment from P.J. McNealy, a research director for Gartner: "Unless there's stunningly tremendous additional content, consumers may not warm to it." Oh you think?
