After two airings, the new castaway drama from Alias creator J.J. Abrams and Damon Lindelof has become one of the highest-rated new shows of the fall television season, the Reuters news service reported. In its second week, the show about plane-crash survivors marooned on a mysterious tropical island drew 17 million viewers, easily dominating its 8 o'clock hour and ranking as the most watched show all night after CSI: NY, the news service reported. It was number one among teens and men aged 18-49.

The second airing of Lost retained 91 percent of the 18.7 million viewers who tuned in to the show's premiere last week and 96 percent of its debut 18-49 audience, the news service reported. Last week's Lost premiere was the first ABC drama to enter the Nielsen top 10 in 18-49 ratings since The Practice in 2001. Lost airs Wednesdays at 8 p.m. ET/PT.
