Production
The series was first announced by DualStar and the then-Disney-owned DIC Entertainment in March 1999. Initially, the series was going to be based on the Trenchcoat Twins personas.

By 2000, the series had become a co-production of DIC and Canal J, under the tentative title Action Girls. 52 episodes were tentatively planned for the series.

After its premiere on ABC in the United States, in November 2001, DIC pre-sold the series internationally to CITV (and later Nickelodeon as well) in the UK, Canal J in France, Mediaset in Italy, YTV in Canada and Fox Kids Latin America.

In April 2002, Televisa in Mexico and RTÉ in Ireland purchased broadcast rights to the series in their respective countries.

Broadcast
From September 2002 – 2003, following the channel's rebrand, Toon Disney reaired the series alongside other ex-One Saturday Morning shows.

In April 2015, Nickelodeon acquired several US broadcast rights to DualStar's content library, including this series, although it was never re-ran on the channel.

DVD releases
In June 2005, Warner Home Video released a single-disc volume called "Misty and Amber vs. Renee la Rouge", featuring 5 episodes of the series focusing on the villain Renee la Rouge. The episodes come with English, Spanish and French audio tracks, as well as featuring a Trivia Challenge and a Villain Bio as bonus features.

In 2016, the series was released to iTunes, but it contained the same episodes only available on the Volume 1 DVD.

Books
The series spun-off a series of books published by Dualstar Books and HarperEntertainment in 2002. In the books, the twins are special agents assigned to solve different mysteries around the fashion and sports world, and have to travel to such cities as New York City, Paris, and Rome to do it.

 * Book number 1: Makeup Shakeup. Setting: New York and Paris.
 * Book number 2: The Dream Team. Setting: Rome.
 * Book number 3: Fubble Bubble Trouble. Setting: The Mall of Malls, a fictional mall that appears to be based on the Mall of America
