If technology firms like Sony and Microsoft have their way, songs and movies will expire after a single play -- unless you pay the copyright holder their due.
The technology that makes this possible known as digital rights management, or DRM will forever change the way we consume media and software, experts believe.
Software and media companies continue to push new content security initiatives, each plugging their own version of DRM that aims to protect content from unwelcomed eyes. In the near future, e-mails, spread sheet programs and Webpage content alike will be secured with digital locks.
Sun Microsystems said this week it plans to roll out new software to protect copyrighted content stored on mobile phones and smart cards. Meanwhile, Warner Music, a division of CNN's parent company AOL Time Warner, released the new Steely Dan album "Everything Must Go" on CD and DVD Audio, the latter being an encrypted, "rip-proof" format.
The biggest market for content security is expected to be corporations, government agencies and hospitals who need to keep sensitive data from falling into the wrong hands. But so far, it's the media companies that have made most noise about DRM.
