Weyland-Yutani

Sponsorship the way you would do it
Weyland-Yutani is a memorable fictional corporation that forms an essential part of the setting of the Alien movie, its sequels and other works set in the same universe. The corporation runs the human colonies outside the solar system, and also has a large presence on Earth. It is only ever referred to as the company, and except for a brief scene in the director's cut version of Aliens, the name Weyland-Yutani is not shown prominently. However, the name did appear in the scripts and on movie props, and could be deciphered on-screen in Aliens and Alien 3, and that is how it was found out by fans of the franchise.
