Syfy has picked up a fourth season of the BBC fantasy series Merlin in a deal with FremantleMedia Enterprises. The series, produced by Shine TV, started its U.S. run on NBC under Ben Silverman. It was canceled after one season and moved to sibling Syfy where it has done solid business in Season 2 and Season 3, recently averaging 1.93 million viewers for its third season, up 12% from Season 2. Meanwhile, VH1 has renewed its first hourlong scripted series Single Ladies for a second season. Both Merlin and Single Ladies will return with originals in 2012.
