Producers aim to target specific audience demographics, like those aged 24-54 who are most likely to have a higher income. Uses and gratification theory explores why people choose certain media for purposes like social needs, entertainment, or gaining knowledge. Reception theory considers how audiences interpret media based on their social positioning and can take dominant, negotiated, or oppositional readings.
