Public service announcement

A public service announcement (PSA) or community service announcement (CSA) is a non-commercial 'advertisement' - typically on radio or television - broadcast for the public good. Although it has been argued that PSAs do some public good, they are often perceived as being a waste of tax money and that it is not plausible to expect the audiences targeted to changes their attitudes and/or actions following a short television or radio spot.
