Yahoo Finance will be featuring interactive stock charts, better message boards, business-related video clips - and offering online publishers the ability to easily add stock charts, quotes and news headlines to their websites, reports CNET. The improvements come some four months after Google introduced its own finance site with interactive charts and similar new features.

For the initial two-month launch period of the Yahoo Finance test, TD Ameritrade will be the official sponsor of the site's video clips, with :15 and :30 pre-roll ads, in addition to banner and graphic ads, reports MediaPost. Video content partners include CNN.com, ABCNews.com, Forbes.com, and SmartMoney, and Yahoo is apparently in talks with a score of others.

The new charts, like Google's, incorporate Flash to more dynamically present data, and visitors can now look up stock info by both company name and ticker symbol, as with Google. Message board discussions will appear as threads rather than chronologically.
