When it comes to content-delivery media, CD-ROM is the new standard. CD-ROM's flexibility also allows for different CD sizes and shapes, creating a level of customization and product-branding over and above other delivery media.
The considerable storage available on CD-ROM and DVD makes them perfect for various multimedia applications. They can be used for something as simple as an electronic brochure with links to your web site (or to a complex database-driven catalog or application updated on an online web server), or they can be used to store to digital videos and animation.
