Blue Sun

In the television series Firefly, Blue Sun is a large, diversified corporation, compared by creator Joss Whedon to a combination of Walmart and Microsoft. The company is broadly hinted as as being less benign than either of those two companies, and plays a role more comparable to that played by Weyland-Yutani in the Alien franchise. It is heavily implied that Blue Sun was responsible for the experiments carried out on River Tam as a subcontractor to the Alliance military, as early (i.e. pre-Serenity attemps to recapture the Tams were led by Blue Sun employees.
