Oswald the Lucky Rabbit is notably associated with which major animation studio?

Oswald the Lucky Rabbit is notably associated with Universal Pictures because he was one of the first characters created by Walt Disney and Ub Iwerks during the early 1920s, specifically for Universal. Oswald was significant in the history of animation as he was one of the first cartoon characters to have a personality and a distinct character design, helping to set the groundwork for future animated characters.

This connection to Universal Pictures is pivotal because it highlights the early collaborations and rights issues that arose in the animation industry. After losing the rights to Oswald due to a contract dispute with Universal, Disney went on to create Mickey Mouse, further emphasizing the impact Oswald had on Disney's career and the animation landscape.

The other studios listed did not have any historical association with Oswald. Pixar and DreamWorks were founded much later and have no direct ties to the creation or distribution of Oswald. Warner Bros., while important in the realm of animation, did not play a role in Oswald’s development or legacy.
