When it comes to ad recall in mobile, entertainment, technology, and retail are the top industry categories, according to a new study commissioned by mobile ad network Greystripe. Based on a March survey of 2,090 U.S. adults conducted by Harris Interactive, it found entertainment ads were recalled by 39%, tech, 36%, retail, 32%, and gaming, 29%.

The study concluded 77 million Americans, including 60% of smartphone owners, recall seeing a mobile ad. Of smartphone users who have seen an ad, 67%, or 39 million, recall the brand category. Younger users were most likely to remember an ad. Two-thirds of users aged 18 to 34 remembered an ad compared to 61% of those 35-54, and 44% of those 55 and over. Recall according to gender was nearly even, with 67% of men remembering ads, and 67% of women.
