Asimov's Science Fiction is an American science fiction magazine edited by Sheila Williams and published by Dell Magazines , which is owned by Penny Press . It was launched as a quarterly by Davis Publications in 1977, after obtaining Isaac Asimov 's consent for the use of his name.

It was originally titled Isaac Asimov's Science Fiction Magazine , and was quickly successful, reaching a circulation of over 100,000 within a year, and switching to monthly publication within a couple of years. George H. Scithers , the first editor, published many new writers who went on to be successful in the genre.

Scithers favored traditional stories without sex or obscenity; along with frequent humorous stories, this gave Asimov's a reputation for printing juvenile fiction, despite its success. Asimov was not part of the editorial team, but wrote editorials for the magazine.
