Effect of Ad Length on Recognition
What is the ideal ad length/exposure time? If an ad is too short, it will not reinforce the audience’s memory. However, as the length or exposure time increases, costs surge. The length of a television commercial has a positive effect on the ad’s memorability (Pieters and Bijmolt 1997), where longer ads give viewers more time and opportunities to attend to and process the message, thus leading to better learning (Batra and Ray 1986; Moore, Hausknecht, and Thamodaran 1986).
