FX gives go-ahead for hot motorcycle club drama

FX is making more vroom for “Sons of Anarchy.”

Motorcycle club drama has drawn a fourth-season renewal in a move that came early but was certainly not unexpected. Skein, which airs at 10 p.m. Tuesday night, is tops in 2010 for a scripted series on basic cable in the 18-49 demo (3.4 million viewers), and it draws 4.9 million total viewers. Across multiple airings during the week, the show’s aud jumps up to 8.6 million viewers.

Created by Kurt Sutter, “Sons of Anarchy” is the most-watched show in the history of the cabler. Season three is airing now; eight episodes remain, and the finale will air Nov. 30. Like the first three, the fourth season will run 13 episodes.

“Sons of Anarchy is the most popular show FX has ever had, and the No. 1 series in basic cable for our key demographic. It is also one of the best, most original series on television,” said FX president and general manager John Landgraf.

Sutter exec produces with John Linson and Art Linson. Skein, which stars Charlie Hunnam, Ron Perlman and Katey Sagal, is produced by FX Prods. and Fox 21.

The success of “Sons” on Tuesday night may account for lower male demo totals on the broadcast side. In the same 10 o’clock timeslot, NBC’s “Parenthood” is down from its spring launch and ABC’s “Detroit 1-8-7″ is off to a rocky start.
