Ideology is a set of attitudes, beliefs and values held in common by a group that are culturally reproduced to sustain a particular way of life. Dominant ideologies reflect what is considered normal or standard in a society at a given time, such as expectations of how certain groups like teenagers, women or the elderly behave or present themselves. The media plays a role in reinforcing dominant ideologies through the representations and portrayals in its content. Audiences need to recognize, challenge, and be aware of the particular world views or interests that may be promoted or challenged in different media texts.
