People Don’t Like Pre-Roll Video Ads, Executives Don’t Either

Companies are rushing to serve up advertisements with online videos, but that doesn't mean anybody is paying attention to the promotions for cars, soap or sneakers. Although increasingly widespread, the short commercial spots that run before videos -- everything from entertainment clips to news spots -- may do as much harm as good, media experts say. Studies show the commercials, known as pre-rolls, often irritate consumers, thus raising the risk they'll ignore the promotion or click to another Web site altogether. A recent study by IBM, titled "The End of Advertising as We Know It," found that 40 percent of the 2,400 consumers and 80 advertising executives it surveyed found ads during an online video segment more annoying than any other format.
