While it's not exactly bringing down the house, "Vampire Diaries" is The CW's top-rated program in this young 2009-10 season, and to reward it, the network has ordered nine more scripts.

The move, while not exactly a pickup, is a very positive sign that The CW could give "Vampire Diaries" a full season order.

"Vampire Diaries" premiered with a 3.1 rating/5 share, according to Fast National ratings from The Nielsen Co., and despite losing 19 percent of its premiere audience, it still remains The CW's hottest show. It's averaging a 2.8/5 over its first two episodes, 40 percent better than its long-standing lead-out, "Supernatural," which is averaging a 2.0/3 in its first two weeks.

"Supernatural," however, was The CW's third highest-rated show based on overnights last week behind only "Vampire Diaries" and "America's Next Top Model."

The CW has picked up additional material from other shows as well including more scripts for "Melrose Place" and a full-season order for "One Tree Hill."

"Vampire Diaries" so far as a 90.3 Stability Index Rating, a measure used by the BlipNetwork to determine how much audience a show is retaining by comparing its highest overnight rating with its average. "Supernatural" is retaining 95 percent of its audience on average.
