Beginning in 1942, Browne worked as managing editor for Ziff Davis publications on Amazing Stories and Fantastic Adventures, both under Raymond A. Palmer's editorship. When Palmer left the magazines in 1949, Browne took over in January 1950. Browne ended the publication of Richard Shaver's Shaver Mystery and oversaw the change in Amazing from a pulp magazine to a digest. He left the magazines in 1956 to move to Hollywood.
Browne's novel Thin Air was twice adapted for television. In 1975 it was used as the basis for a first-season episode of The Rockford Files titled "Sleight of Hand." In 1982 it was the basis for a second-season episode of Simon & Simon of the same name as the novel.
