Which multimedia audience is targeted with large font, simple vocabulary, and a combination of many types of media?

Children

Explanation:

Children are the demographic that would be targeted with media that has these characteristics. Large font is useful for children because their reading skills are often very basic. By using large font, we ensure that they are able to read the message easily. Moreover, because of this lack of familiarity with written language, children often require simple vocabulary in order to understand a message. Finally, a combination of many types of media ensures that the message gets through even when the children are distracted.
