Having focused on optical disc media since its inception, Sony DADC (Digital Audio Disc Corp.) didn't really feel the negative effects of the waning VHS and cassette tape industry. A subsidiary of Sony Corp., Sony DADC manufactures DVDs, audio CDs, Blu-Ray discs, and PlayStation UMDs (Universal Media Discs) that contain replicated content (i.e music, software); it also offers packaging and supply chain services. In addition, the company develops technologies intended to prevent illegal disk copying and offers a variety of digital services, including digital content storage. Established in 1986, Sony DADC operates globally through 28 facilities located in Europe, Asia, Australia, Japan, and the Americas.
In order to help its clients (which includes other Sony divisions, as well as software, DVD distribution, and film production companies, among others) have more control over proprietary content , Sony DADC has been expanding its digital service offerings to include anti-pirating technologies for CD-ROMs and other optical disc media. The company's PID technology (Postscribed ID) automatically registers software on CD-ROMs so that the software cannot be downloaded again on other computers. It also makes SecuROM, a coded technology that differentiates between an original disk and a copied disk and inhibits the function of the copied disk.
The company also offers products that help companies track the behavior of disk users. Its eBridge application, which is built into DVDs or CDs, reports users' behavior back to marketing departments, surveyors, and other parties that are interested in knowing how consumers are using their content. – less
