Fictional corporations are imaginary companies created for storytelling in various media, including books, movies, and video games. They often serve as a backdrop for the plot, representing themes like corporate greed, innovation, or dystopia. Examples include Weyland-Yutani from the Alien franchise and Umbrella Corporation from the Resident Evil series. These corporations can reflect real-world issues, such as ethical dilemmas in business practices or the impact of technology on society. By exaggerating certain traits, fictional corporations can critique or satirize actual corporate behavior, making them a powerful tool for commentary in popular culture.
