Themed on supernatural gifts, its lead character, Allison DuBois, is a medium employed as a consultant for the Phoenix, Arizona district attorney's office. Allison and her husband Joe are the parents of three daughters, all of whom inherited Allison's gift. The show was initially based on the experiences of medium Allison DuBois, who claims she has worked with law enforcement agencies across the country in criminal investigations.
Medium was created by Glenn Gordon Caron and was produced by his company Picturemaker Productions and Kelsey Grammer's Grammnet Productions in association with Paramount Television from 2005–06, CBS Paramount Television from 2006–09, and finally CBS Television Studios from 2009 until the series ended.
The series aired on NBC during its first five seasons before switching to CBS for the sixth and seventh seasons. The production division of CBS had assumed production of Medium in 2006 after absorbing the television arm of the Paramount Pictures film studio. Paramount's home entertainment arm still held DVD distribution rights in conjunction with CBS DVD.Overview from themoviedb.org
