Marketers looking to capitalize on the exploding online video space should take note: nearly 79 percent of users report being annoyed by ad units embedded in the content, according to a recent survey from Burst Media.

The survey, which was reported in The New York Times, found that more than half of the 2,600 people polled recalled seeing in-stream ads. While that may seem like good news for marketers, the bad news is that more than three quarters of respondents said in-stream ads are intrusive. Half of those surveyed said the ads actually disrupt their internet use. About the same number of respondents reported turning off the content once the ad unit disrupted their viewing experience.

The survey did find that younger viewers tend to be less annoyed by in-stream ads, with 57 percent of those between the ages of 18 and 24 reporting that they continue to watch content after the in-stream ad appears. Unfortunately, Burst found that younger people tend to have lower recall rates.
