This document discusses media codes and conventions. It defines media language as how media texts are conveyed to audiences. There are various technical codes that frame visual media, such as camera angles and movement. Symbolic codes require audience inference. Semiotic theory examines literal and implied meanings in signs and symbols. Media codes and conventions establish themes, characters, settings, narratives and other standard elements that audiences expect. Theories also discuss how media can influence or manipulate audiences, and how audiences selectively consume media. Producers and stakeholders have commercial and financial interests to consider in their relationships with media and audiences.
