Although accounting for more than half of all online video content consumed – user generated videos will make up just 15% of total revenues. These are the latest findings from Screen Digest, the media analyst firm, which today releases its latest report on the UGOV market.

Screen Digest believes that advertising will be the principal source of revenue for UGOV sites. In the US ad revenues will grow from $200m in 2006 to almost $900m by 2010. This represents only 15% of all online video revenues.

So whilst there is no shortage of consumers ready to use these sites, the key challenge facing the many companies that now operate in the UGOV arena is finding a business model that will make them financially viable. According to Screen Digest, there are five business models currently being used to make money from UGOV:

• Advertising
• Content Licensing
• D Commerce (digital sales and rental of premium movie and TV content)
• Subscriptions
• Technology Licensing

• Total US online video streams and revenue forecasts
• The UGOV value chain and potential business models
• Analysis of UGOV file and delivery formats
• Detailed list of UGOV sites by category
• UGOV market forecasts for the US market
