Since the 1980s or even earlier, there have been quite a few campaigns in this little island, here's a list of the ones that I have found to be memorable:

Around 1979, this campaign was to encourage Singaporeans to be more courteous, and basically be more polite, sparing a thought for others; to create a pleasant social environment. It lasted for a period of 10 years. Its mascot was called, Singa the Courtesy Lion. Banners and posters were hung in public places like bus stops, shopping center and open-air markets. Leaflets, handbooks and pamphlets were also handed out to educate the people further.Essay competitions in all four national languages (English, Chinese, Malay, and Tamil) were arranged to reach out to children as well. Soon, an assortment of memorabilia consisting of mugs, plushies, key chains, notepads and vases that featured the mascot, Singa, were introduced; along with courtesy songs, fables, and slogans.

The Keep Singapore Clean campaign lasted just one month during the year 1968, as the police, health officials went around to "preach" the evils of filth. What really had an impact about the campaign was its follow-up where those who were caught littering were dealt with harsh penalties - getting fined and made to clean up litter wearing bright colored overalls.

The outbreak of SARS during 2003 birthed the 'Singapore's OK' Campaign, which was aimed to increase the public's awareness of the importance of personal and environmental hygiene.

This campaign was to educate Singaporeans on the importance of water, to conserve and not to waste it; as Singapore imports most if its water supply from abroad. Water supplies would be cut off to thousands of households, to rehearse for rationing even if there was no immediate shortage or drought.In 1998, there was an element of surprise because unlike previous years' campaigns affected households were not informed before the cut, and there were no trucks distributing water to those homes
