Showtime cancels tara. U.S. cable network Showtime has decided not to move forward with "United States of Tara."The Toni Collette comedy, which centers on a mom who suffers from multiple personalities, will be ending after its third season ends this summer.

Tara, created by Oscar-winning screenwriter Diablo Cody and executive produced by Steven Spielberg, premiered in 2009 to solid ratings, but began to diminish in viewership as seasons progressed.

It premiered its current season to 411,000 total viewers and a 0.2 rating in the adults 18-49 demographic, down significantly from its Season 2 launch, when it averaged 816,000 and a 0.4.

Collette won an Emmy in 2009 and a Golden Globe in 2010 for her performance.

It's a mixed bag for Showtime, as the network announced on Monday that Edie Falco's "Nurse Jackie" will be back for a fourth season.
