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.

[33] According to editor Paul Levitz, at the time of the cancellation there were still no Huntress stories in production, and the slated content for Showcase #107–109 was Gerry Conway's Western adventure The Deserter.

[35] For the most part edited by Karen Berger (and for a short time by Sal Amendola), the series gave new writers and artists their first professional opportunity in the comics industry.

Notable creators who made their DC debuts with New Talent Showcase include Mark Beachum, Norm Breyfogle, Tom Grindberg, Steve Lightle, Mindy Newell, and Stan Woch.

For the first two years (1993–1994), Showcase featured characters and concepts from the Batman family of titles with an emphasis on villain-centric one-off stories.

Showcase '94 #4-5 were part of a crossover with Robin, involving Tim Drake and Huntress fighting a masked priest/vigilante attempting to eliminate his evil mob boss sister's criminal empire.

This included a story involving the Matrix Supergirl that led into her ongoing series written by Peter David (Showcase '96 #8) and a two-part story involving the Post-Zero Hour Legion of Super-Heroes (#11-12) which featured the first post-Zero Hour meeting of Brainiac 5 and his ancestor Vril Dox and the villain Brainiac, which ultimately served as the final storyline as the series was canceled with #12.

In 2005, DC began publishing thick, black-and-white reprints of older material under the umbrella title Showcase Presents.
