SAGE was founded in 1965 in New York City by Sara Miller (later Sara Miller McCune) with Macmillan Publishers executive George D. McCune as a "mentor"; the name of the company is an acronym formed from the first letters of their given names. SAGE relocated to Southern California in 1966, after Miller and McCune married; McCune left Macmillan to formally join the company at that time. Sara Miller McCune remained president for 18 years, shifting to board chairman in 1984 (and still retains the title of executive chairman). The couple continued to develop the company together until George McCune's death in 1990.
In 2008, SAGE along with two other companies sued Georgia State University for alleged copyright infringement due to faculty providing excerpts of materials to students. The case concluded in 2020 with the publishing companies losing.
In 2019, products by SAGE like Lean faced opposition by part of the academic community for being owned by a for-profit, as opposed to open data, open source and non-profit products like Unpaywall which facilitates usage of open access works.
SAGE Publishing was a founding member of the Open Access Scholarly Publishers Association (OASPA) when it was established in 2008. In November 2013, OASPA reviewed SAGE's membership after the Journal of International Medical Research accepted a false and intentionally flawed paper created and submitted by a reporter for the journal Science as part of a "sting" to test the effectiveness of the peer-review processes of open access journals . SAGE's membership was reinstated at the end of the six month review period following changes to the journal's editorial processes.
