The document discusses three examples of how different media products represent teenage social groups: 1) A character from a film shown as fashionable with casual footwear, representing teenagers ages 15-17. 2) A crying girl in a film shown as frightened with pink clothing, representing children and teenagers. 3) A school girl in a news story shown in uniform, representing school girls up to age 16. The discussion analyzes how these representations use costume, makeup, and context to suggest age and develop characters, and how the document's media product aimed for a more sophisticated teenage character than options showing younger, more innocent depictions.
