“…A gullible consumer may believe that a celebrity recommends a product because he/she really is convinced of the quality of the product (Silvera & Austad, 2004). Several scholars warn about persuasion by in-program endorsement without audience awareness and plead for regulation of product appearance in programs (Benjamin, 2005;D'Astous & Chartier, 2000;Hackley, Tiwsakul, & Preuss, 2008;Kuhn et al, 2010;Law & Braun, 2000). This may be disadvantageous for advertisers and marketers because in-program endorsements are presumably most effective when people are not aware of their influence, thus avoiding rebuttal or a negative evaluation of the message (Balasubramanian, Karrh, & Patwardhan, 2006;Law & Braun, 2000;Matthes, Schemer, & Wirth, 2007;Morton & Friedman, 2002).…”
