Los Angeles-based Revver has opened up its "viral video" marketplace, saying that it will allow people to create, sponsor, and share viral videos linked to advertising. The firm said that it has released its 1.0 product, having been in beta since 2005. The site provides users with a percentage of the advertising revenue generated from the site. Revver is one of the online video sharing and user-generated video site focused on adding a revenue component based on advertising. The move comes on the heels of the addition of advertising channels on YouTube, a similar advertising revenue-sharing deal at EEfoof, and the announcement yesterday by Los Angeles-based Break.com that it will share its advertising revenue directly with producers of videos featured on its web site, too.
