Here is how th SGU describes itself today:
The Skeptics’ Guide to the Universe is produced by SGU Productions, LLC – dedicated to promoting critical thinking, reason, and the public understanding of science through online and other media. The first episode of the SGU podcast went online on May 4th, 2005. It soon became a popular science/skeptical podcast, and remains one of the most popular science podcasts on iTunes.
Somewhat different emphasis here. Does anyone know why they changed their self-description?
LLC is an abbreviation for "Limited Liability Corporation."
Following the recent lawsuit against Steve, I would speculate
that they wanted to insulate themselves, personally, and the NES from any legal liability in case there are more nuisance suits, so they made a very reasonable change in the SGU's legal status and that's reflected in their description.
Also, it probably helps to make it clear they are promoting critical thinking, etc. as a purpose rather than doing something (advertising; making claims that could be false; promoting products, etc.) that could open the door for more legal woes.
