The document discusses techniques used in charity advertising campaigns. It provides context about the charity Shelter, including that it aims to help people with homelessness and housing issues. Shelter launched a poster advertising campaign in 2011 to encourage people at risk of losing their home to seek advice earlier. The campaign was created pro bono to raise awareness of homelessness arising from today's economic situation, using slogans like "but where will we live?" to get the message across directly. Generic codes and conventions of charity ads are discussed, such as creating sympathy, empathy and shock for the subject, using the charity's name and logo, sombre tones, and calls to interact with the charity.
