Harris Publications would be the best company to publish the author's magazine because it publishes over 75 titles on a wide range of topics including music, exercise, and small business. In particular, the author's magazine, which contains exercise facts and health help, aligns well with Harris Publications' titles like XXL and Exercise & Health. While Vibe magazine is also a well-recognized company, the author's research found their magazine would be a better fit with XXL's target audience and mix of music and exercise content.
