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.
The magazine shrank to the conventional 8Â½Ã11 inches in 1971. The magazine was sold by the original owners to Clay Felker in 1977, who reinvented the magazine as a fortnightly in 1978, under the title of Esquire Fortnightly. However, the fortnightly experiment proved to be a failure, and by the end of that year, the magazine lost US$ 5 million.
