As a significant part of the cause of the public good, it is noncommercial and does not aim at making profit. The themes of public service advertisements generally come from the daily life of ordinary people, such as health, safety and environment protection.Its objectives are raising public awareness of ethics and changing public attitudes towards social issues. The earliest public service advertisement in China appeared in 1986. From then on, its social influence heightened gradually. Last year, CCTV hosted China' s first public service advertising competition, appealing to people in all walks of life to concern about and participate in the cause of the public good.
