Yahoo’s (YHOO) ambitions to expand its reach on the web have now come into clearer focus now as The Wall Street Journal reports that the company is considering buying a major stake in Dailymotion, the second-largest video sharing website on the Internet after YouTube. Unnamed sources have told the Journal that buying a stake in the French video-sharing site “would help U.S.-based Yahoo to gain a bigger toehold in online video in parts of Europe and Asia.” The Journal’s sources also say that Yahoo initially plans to buy as much as 75% of the site while retaining the option to purchase the entire company, which could be valued at $300 million.
