Media ownership has a significant impact on the successful distribution of films. Large companies like Time Warner, which owns Warner Bros., have a major advantage over smaller companies due to their ability to independently distribute films on a massive global scale through their ownership of production and distribution subsidiaries. For example, Warner Bros. was able to profit greatly from The Dark Knight Rises through extensive traditional and social media marketing campaigns made possible by their large size and resources. In contrast, smaller companies like Vertigo and Warp have much more limited distribution capabilities and rely heavily on film festivals and DVD sales rather than wide theatrical releases, making it difficult to compete with major studios.
