Just because you put your video ad on YouTube does not mean you don't have to meet guidelines for truth and accuracy according to the National Advertising Division of the Council of Better Business Bureaus. The watchdog agency for the first time ruled on the existence of ads on video-sharing networks and said the rules aren't all that different. The ruling came as a result of a complaint from Euro-Pro, a vacuum cleaner maker who said that videos on YouTube from Dyson were inaccurate when making comparisons between the two brands. Dyson pulled the ad before the ruling. The case established an important precedent as more marketers use video sharing sites to connect with their consumer base.
