Highlights for Children, often referred to simply as Highlights, is an American children's magazine. It began publication in June 1946, started by Garry Cleveland Myers and his wife Caroline Clark Myers in Honesdale, Pennsylvania (the present location of its editorial office). They both worked for another children's magazine, Children's Activities, for 12 years before leaving to start Highlights.
It was first published in 1974 by Larry Flynt. It was a step forward from the Hustler Newsletter, which was cheap advertising for his strip club businesses at the time. The magazine grew from a shaky start to a peak circulation of around 3 million; it has since dropped to approximately 500,000.
