Bauer Media would be the best publisher for the student's jazz magazine due to their wide range of music magazines and social media presence. While Bauer's current magazines like Q target older audiences, publishing a jazz magazine aimed at 15-19 year olds would help Bauer reach a younger demographic. Bauer does not currently have a jazz magazine. Future Publishing could also be a suitable option since they have some gaps in their music magazine offerings, but Bauer remains the top choice.
