Documented cause
Yahoo! 360° launched in March 2005 as a social networking and blogging platform to compete with MySpace and Friendster. It combined profiles, blogs, and friend connections. Despite Yahoo's massive user base, 360° never achieved significant adoption. It was shut down in July 2009 as Facebook made the entire MySpace-era social model obsolete.
Lesson
“Access to a large user base does not guarantee adoption of a new product if the product is not genuinely better.”

FAQ
Why did Yahoo fail at social networking?
Multiple reasons: Yahoo was an advertising portal company trying to build a social product. The incentives, culture, and execution were misaligned. Facebook was built for social from day one with a clear, constrained use case (college networks). Yahoo built 360° defensively, not offensively.
