The effects of ad length, ad position, and ad-context congruity on brand name recognition in an online in-stream video advertising context were investigated. Video ads and video programs were selected from YouTube as stimuli. Findings from a laboratory experiment indicate that long ads enhance recognition. Mid-roll ads lead to better brand name recognition than pre-roll and post-roll ads because of attention spillover. However, a mid-roll ad is futile when the ad is unrelated to the video content. In contrast, post-roll ads can improve brand name recognition in an incongruent context.
