RT Journal Article SR Electronic T1 The Power of Citizen-Group Public-Policy Advertising JF Journal of Advertising Research JO J Advert Res FD WARC SP 405 OP 420 DO 10.2501/JAR-52-4-405-420 VO 52 IS 4 A1 Daniel Bergan A1 Genevieve Risner YR 2012 UL http://www.journalofadvertisingresearch.com/content/52/4/405.abstract AB Issue advertisements are advertisements designed to change public opinion about a social issue rather than advocate or oppose a candidate or ballot question or sell a product or service. What effect do these advertisements have on perceived importance of the advertised issue and attitudes and knowledge about the featured policy? Results from an online experiment studying the effect of online issue advertisements suggest that issue advertisements can increase the salience of and knowledge about an issue. Issue advertisements can also persuade about the merits of a policy but only among individuals without attachments to major political parties.
