What is the name of the fictional corporation controlling the Animus in Assassin's Creed?

Abstergo Industries is the fictional corporation controlling the Animus in Assassin's Creed.

Abstergo is presented as a powerful multinational company whose public business activities conceal its connection to the modern-day Templar Order. It develops and operates Animus technology, which allows users to access genetic memories inherited from their ancestors.

In the original game, Desmond Miles is held by Abstergo and forced to use the Animus to relive Altaïr's memories. The company therefore provides the modern framework for the historical sequences while also acting as a major antagonist.

Abstergo is not the name of the machine. The machine is the Animus, and different versions appear throughout the series. The distinction matters because Abstergo is an organization, while the Animus is the technology that connects modern users to ancestral memories.
