The document discusses the history and development of advertising in China. It notes that early advertising used pictures instead of text due to high illiteracy rates. New government regulations in the 1950s required advertising to emphasize social responsibility over profits. Private businesses disappeared and state-run advertising agencies took over most advertising tasks. Debate continued over allowing commercials on radio and television. Advertising re-emerged in China in 1979 and has since grown with the expanding middle class. However, certain topics like sex, disrespecting authority, or competitive products remain sensitive.
