Brightcove's new video syndication and ad network has picked up another client, as Dow Jones, publisher of the Wall Street Journal Online, MarketWatch.com and Barron's Online, has begun using its services.

Dow Jones has been using Brightcove's services with all three sites to distribute news, commentary and lifestyle video clips that are monetized through pre-roll video and banner ads, ClickZ reports. Microsoft and Lexus has exclusively sponsored the video content for the three sites, and half a million video streams were delivered through Brightcove in the first month.

Brightcove works to facilitate categorization and searching of the content it helps distribute by publishing that content into a set of HTML documents with unique URLs that can be crawled by search engines. Dow Jones can tag this content with keywords using the system to optimize its video for search and RSS feeds, and set up rules defining how the content will be distributed within its own properties.

Dow Jones Online plans to work with Brightcove to develop additional video players and related ad offerings.
