I don't think I'd be a fan of these, but interesting nonetheless...

The Walt Disney Company has begun to sell Disney movies on disposable DVDs in a four city test to see if consumers will pick up a limited life DVD rather than renting and returning to a video rental store. When the Flexplay DVD , shown in this undated publicity photograph, is removed from its packaging and exposed to air, a process begins that renders the disc unplayable after the pre-set viewing period elapses. The disc becomes opaque and thereby unreadable when the disc changes color from red to black. The DVD's will carry a suggested price of $6.99.
