LOS ANGELES (thefutoncritic.com) -- "The Division," one of Lifetime's longest running dramas to date, has been canceled after four seasons.

The veteran Sunday drama averaged 2.0 million viewers for its most recent season, down 20% in year-to-year comparisons (2.5 million from January to June in 2003).

"For four years, 'The Division' was a popular, critically acclaimed drama series which comprised a key part of our Sunday night drama block along with 'Strong Medicine,'" a Lifetime spokesman told The Hollywood Reporter. "However, we felt that the show had, as all television programs eventually do, run its course, and it was time to offer our viewers another option."

The move leaves the cable channel with three scripted series on its schedule - "Strong Medicine," "Wild Card" and "Missing" - the latter of which has also been picked up for five additional episodes.

The news brings "Missing's" season total to 18 episodes, the same as fellow sophomore entry "Wild Card," but short of the network's flagship drama "Strong Medicine." "Missing" currently averages 2.2 million viewers on Saturday nights for the cable channel.

"The Division," which comes from Viacom Productions, was created and executive produced by Deborah Joy Levine.
