IPC has been associated with magazines targeting a variety of audiences over the years, including magazines focused on sports like horse riding, shooting, yachting, cycling, and fishing. They initially targeted middle-aged men but expanded to target women through magazines about gardening, photography, railways, and women's interests. In later decades, IPC collaborated with additional magazines focused on sports, boating, parenting, and home/garden topics, continuing to target middle-aged men and women.
