Good Housekeeping is an American women's magazine featuring articles about women's interests, product testing by The Good Housekeeping Institute, recipes, diet, and health, as well as literary articles. It is well known for the "Good Housekeeping Seal", a limited warranty program that is popularly known as the "Good Housekeeping Seal of Approval". Good Housekeeping was founded in 1885 by American publisher and poet Clark W. Bryan. By the time of its acquisition by the Hearst Corporation in 1911, the magazine had grown to a circulation of 300,000 subscribers. By the early 1960s, it had over 5 million subscribers and was one of the world's most popular women's magazines. History and profile On May 2, 1885, Clark W. Bryan founded Good Housekeeping in Holyoke, Massachusetts as a fortnightly magazine. The magazine became a monthly publication in 1891. The magazine achieved a circulation of 300,000 by 1911, at which time it was bought by the Hearst Corporation. It topped one million in the mid-1920s, and continued to rise, even during the Great Depression and its aftermath. In 1938, a year in which the magazine advertising dropped 22 percent, Good Housekeeping showed an operating profit of $2,583,202, more than three times the profit of Hearst's other eight magazines combined, and probably the most profitable monthly of its time. Circulation topped 2,500,000 in 1943, 3,500,000 in the mid-1950s, 5,000,000 in 1962, and 5,500,000 per month in 1966. 1959 profits were more than $11 million. Good Housekeeping was one of the "Seven Sisters", a group of women's service magazines, and is one of the three of them still published in print. In 1922, the Hearst Corporation created a British edition along the same lines, named British Good Housekeeping. Famous writers who have contributed to the magazine include A. J. Cronin, Betty Friedan, Frances Parkinson Keyes, Clara Savage Littledale, Edwin Markham, Somerset Maugham, Edna St. Vincent Millay, J. D. Salinger, Evelyn Waugh, and Virginia Woolf. Other contributors include advice columnists, chefs, and politicians. Good Housekeeping Research Institute In 1900, the "Experiment Station", the predecessor to the Good Housekeeping Research Institute (GHRI), was founded. In 1902, the magazine was calling this "An Inflexible Contract Between the Publisher and Each Subscriber." The formal opening of the headquarters of GHRI – the Model Kitchen, Testing Station for Household Devices, and Domestic Science Laboratory – occurred in January 1910. In 1909, the magazine established the Good Housekeeping Seal of Approval.
