I've already commented on Answers in Genesis, Institute for Creation Research, Access Research Network, the Creation Evidence Museum, Creation Illustrated Ministries, Creation Moments, Creation Research Society, and Creation Worldview Ministries. Now, the Discovery Institute.
The Discovery Institute is a Seattle-based think tank founded by Bruce Chapman, former secretary of state for the State of Washington and former deputy assistant to Ronald Reagan. He founded DI in 1990, initially focused on regional issues such as transportation and communication. The DI's transportation arm, called the Cascadia Project, received several million dollars in funding from the Bill and Melinda Gates Foundation. In 1996, Chapman and political scientist John G. West secured funding from C. Davis Weyerhauser's Stewardship Foundation, Howard Ahmanson, and others to create an organization within DI called the Center for Renewal of Science and Culture "seek[ing] nothing less than the overthrow of materialism and its damning cultural legacies" and promoting "intelligent design." The initial DI research fellows were Steven Meyer, William Dembski, Michael Behe, Jonathan Wells, and Paul Nelson, with Meyer and West as co-directors of CRSC and Phillip Johnson as an advisor. The name of the center was subsequently shortened to the Center for Science and Culture (CSC).
In 1999 the DI's "Wedge document" was leaked to the public, the circumstances of which became known in a 2006 story in the Seattle Weekly. You can find much more about the Discovery Institute at The Panda's Thumb blog.
The financial figures below are for the Discovery Institute as a whole, not the CSC specifically.
As usual, the baseline financial information (1997) is from John R. Cole's "Money Floods Anti-Evolutionists' Coffers" in Reports of the National Center for Science Education 20(1-2, 2000):64-65:

The Discovery Institute is an organization with considerable revenue, allowing it to pay extremely lucrative salaries to its senior management and employees. It has shown growth over the years, though revenue dipped in 2004. It has been influential in media coverage of intelligent design, though it has yet to fulfill its promises of scientific research supporting intelligent design and has suffered major defeats in the legal arena. Despite its high revenue, it is still smaller than Answers in Genesis or the Institute for Creation Research, which appear to me to continue to have better grassroots support than the Discovery Institute.
