It focused on topics in the science fiction genre such as literature, film, and artwork, but also addressed topics in other genres such as fantasy, young adult, and horror fiction. The site offered readers several weekly and monthly series such as book reviews, link roundups of author interviews and profiles, round table discussions on various topics (termed "Mind Melds"), links to currently free speculative fiction, contests, and notifications of various events and things that the editors found interesting.
The website was launched in 2003 by John DeNardo and JP Frantz after they noticed a lack of blogs focusing on science fiction. They decided to launch a blog where they could discuss science fiction and related genre writings, events and ideas that were interesting to them. As the website's popularity grew, they began to incorporate more original content and hired additional staff members as well as brought in new contributors.SF Signal published three podcasts: SF Crossing the Gulf,The Three Hoarsemen, and The SF Signal Podcast.
In May 2016, DeNardo and Frantz announced the end of SF Signal because of the blog's increasing demands on their time.
