Ads that interrupt streaming video are getting on the nerves of audiences — and beginning to impact the content they support.

The findings come from a survey of online video audiences by Burst Media.

78 percent of viewers find ads in streaming video intrusive. About half say video ads disrupt their overall online experience.

Worse, more than half reportedly turn away from the video they're watching once it's interrupted with an ad.

Just over 15 percent said they leave the site completely when an ad appears.

Women were more irritated than men, with 53 and 48 percent respectively calling in-video ads disruptive. The report comes in disappointing contrast to a previous study that found users are happy to deal with advertising as long as content is otherwise free.

Online video watchers between 18 and 24 were more accepting, with almost 58 saying would continue watching ad-supported videos.

Unfortunately for brand managers, 69 percent of survey respondents said the video ads made no more or less impression on them than other ads on the same site.
