"'Supernatural' has shown some growth, however. The show earned a 1.5/2 to kick off February sweeps, but came in this past reporting period with a 1.7/3, a 13 percent jump. It was the only genre show to improve its numbers from the previous sweeps period. "Supernatural" also is even with its November sweeps comparative, showing that audiences are staying put with the Winchester Brothers."
