Showtime renews 'United States of Tara'

Showtime has given a second season to "The United States of Tara."

The premium network has renewed the Toni Collette comedy about a woman with multiple personalities for another round.

"Tara" has averaged 2.1 million per week, including repeat airings, which is better than "Dexter" and "Weeds" in their first seasons (the "Tara" number also doesn't include DVR use or on-demand viewing). Helping matters: Sunday night's fourth episode climbed 15% over the previous week.

As for Showtime's other current series, "The L Word" is already in its final season and "Secret Diary of a Call Girl" has a third season coming as part of the show's original acquisition deal.
