Marvel Entertainment is the current leader in the comic book industry with a 39.98% retail market share and 46.67% unit market share. However, to maintain this leadership, the company needs to diversify its characters and target markets to avoid potential backlash over a lack of diversity. The analysis recommends Marvel introduce new diverse characters across ethnicity and capabilities into its comics first before debuting them in films. This would help broaden Marvel's target market and secure its position as the best in the industry.
