Here's a short story:

National Geographic, formerly the National Geographic Magazine, is the official magazine of the National Geographic Society. It has been published continuously since its first issue in 1888, nine months after the Society itself was founded. It primarily contains articles about science, geography, history, and world culture. The magazine is known for its thick square-bound glossy format with a yellow rectangular border and its extensive use of dramatic photographs. Controlling interest in the magazine has been held by 21st Century Fox since 2015. 

The magazine is published monthly, and additional map supplements are also included with subscriptions. It is available in a traditional printed edition and through an interactive online edition. On occasion, special editions of the magazine are issued. 

As of 2015, the magazine was circulated worldwide in nearly 40 local-language editions and had a global circulation of approximately 6.5 million per month according to data published by "The Washington Post" (down from about 12 million in the late 1980s) or 6.7 million according to National Geographic. This includes a US circulation of 3.5 million. 

The current Editor-in-Chief of the "National Geographic Magazine" is Susan Goldberg. Goldberg is also Editorial Director for National Geographic Partners, overseeing the print and digital expression of National Geographic’s editorial content across its media platforms. She is responsible for News, Books (with the exception of National Geographic Kids books), "National Geographic Traveler" magazine, "National Geographic History" magazine, Maps, and all digital content with the exception of National Geographic Kids. Goldberg reports to Declan Moore, CEO of National Geographic Partners. (End of story)
