Television advertising has played an important role in transmitting brand information to consumers for the past several decades. However, technological and social developments have led marketers to seek new advertising formats to effec- tively deliver their messages. Global television ad expendi- tures are expected to grow by 2.5% year on year, while spending on Internet advertising will increase by 13.9% (Warc 2013). From 2006 to 2012, only digital video advertising showed continuous growth as a percentage of total Internet advertising revenues in the United States (Interactive Advertis- ing Bureau and PricewaterhouseCoopers 2013). These trends show that marketers and advertisers have gradually increased their spending on online video advertising. Furthermore, video ad view volume increased by 47% from 2011 to 2012, which is more than double the growth rate of video views (23%) (FreeWheel 2013). This implies that users are watching more Web-based video ads than ever.
