Although video-sharing sites have been under fire recently for copyright and intellectual property infringement, advertisers cannot shirk away from the impact of successful viral videos for interactive campaigns.

Campaigns that get the most buzz in cyberspace tend to be forwarded and passed on through sites such as YouTube or MySpace which allow users to forward videos to friends or post them on their blogs.

While big-name CEOs such as Viacom's Philippe Dauman contest that advertisers want more control over their content to the extent of pulling down 100,000 video clips, some media companies told Variety they wouldn't be in a rush to do that if a show that wasn't doing so well in the ratings could use the promotion.

A new report from Feed Company -- a video-view optimization firm -- found that an increasing number of advertisers are adding social video to their online marketing formula.

"Advertisers recognize the value of having their brand video content exposed to the millions of users populating video share sites," said Josh Warner, president of Feed Company.

Some of the tips Feed Company suggests for advertisers wanting to invest in social video include having video content and campaign creative be consistent with each other and to commit video to being a part of the social conversation. For more of the report, Social Video 101: A Primer" click here.
