This document discusses how media producers select content and define their target audiences. It provides examples of how different elements like images, words, colors, and fonts are used tailored to specific audiences. Images on the front covers of magazines are carefully chosen to represent the magazine's content and attract their target readers. Captions, headlines, and other text elements are also used to shape how audiences interpret and understand images. The layout, color schemes, and other conventions established "codes and rules" that publishers follow to engage their target demographics. Feedback from focus groups, panels, and complaints help publishers evaluate audience reactions and make improvements.
