Microsoft - As of 2006, Microsoft employees, not including Bill Gates, have given over $2.5bn dollars to non-profit organizations worldwide, making Microsoft the worldwide top company in per-employee donations. Technical reference for developers and articles for various Microsoft magazines such as Microsoft Systems Journal (or MSJ) are available through the Microsoft Developer Network, often called MSDN. MSDN also offers subscriptions for companies and individuals, and the more expensive subscriptions usually offer access to pre-release beta versions of Microsoft software. In recent years, Microsoft launched a community site for developers and users, entitled Channel9, which provides many modern features such as a wiki and an Internet forum. Another community site that provides daily videocasts and other services, On10.net, launched on March 3, 2006.
