CD-Roms / DVDs / WWW

In the past, the word "multimedia" made many users think of CD-ROMs and later DVDs, not Web sites. But now true multimedia has come to the Web with the increased online use of the rich media and interactivity once reserved for CDs.

The Web is just one way to present multimedia along with CDs, DVDs, and other platforms.

Programs such as Director and Flash have tremendously enhanced the ability to use the WWW for multimedia presentations

Web surfers who still use a modem, the slow download speed can make the online multimedia experience sometimes frustrating.
