Tony Soprano, it now turns out, got shot down in more ways than one last Sunday. According to the latest Nielsen figures, Sunday's sixth-season opening episode of The Sopranos averaged 9.5 million viewers, down a whopping 22 percent from its average last season. The dropoff was attributed to competition from ABC's Desperate Housewives, which itself took a big hit in the ratings because of the Sopranos' competition, recording 22.2 million viewers, its smallest audience since December 2004.
