Showcase stood out from other tryout series in that it maintained its own readership readers who liked a feature would buy the series when it came out, but would often continue buying Showcase as well. It was the first American comic book appearance of the character. No, which had been published in British Classics Illustrated, and published it as an issue of Showcase. In 1962, DC purchased an adaptation of the James Bond novel and film Dr. The series began in March–April 1956 and saw the first appearance of several major characters including the Silver Age Flash, the Challengers of the Unknown, Space Ranger, Adam Strange, Rip Hunter, the Silver Age Green Lantern, the Sea Devils, the Silver Age Atom, the Metal Men, the Inferior Five, the Creeper, Anthro, Hawk and Dove, Angel and the Ape, the Silver Age Spectre, and Bat Lash.

Showcase featured characters in either one-shot appearances or brief two- or three-issue runs as a way to determine reader interest, without the financial risk of featuring 'untested' characters in their own ongoing titles. The series ran from March–April 1956 to September 1970, suspending publication with issue #93, and then was revived for eleven issues from August 1977 to September 1978. Showcase is regarded as the most successful of such tryout series, having been published continuously for more than 14 years, launching numerous popular titles, and maintaining a considerable readership of its own. The general theme of the series was to feature new and minor characters as a way to gauge reader interest in them, without the difficulty and risk of featuring untested characters in their own ongoing titles.
