What is Multimedia?
Multimedia comes in many different formats. It can be almost anything you can hear or see, like images, music, sound, videos, records, films, animations, and more.
Web pages often contain multimedia elements of different types and formats.
Browser Support
The first web browsers had support for text only, limited to a single font in a single color.
