Walt Disney became the parent company of Marvel Entertainment in 2009 for $4.24 billion. This deal allowed Disney to further expand its dominance in the film industry through horizontal integration. Disney and Marvel are successful due to their popular characters like Mickey Mouse and The Avengers. Some impacts of the deal include Disney gaining power as a monopoly and combining two large audiences. However, issues could arise from Disney not fully owning all Marvel characters and being inexperienced with comic books.
