Ratings: A&E's 'Intervention,' Showtime's 'Dexter'

Monday's sixth season premiere of A&E's "Intervention" was the documentary series' most-watched premiere yet. The episode was seen by 2.2 million viewers (1.7 million among adults 18-49), up 5% among viewers and 13% in the demo.

Sunday's third season finale for Showtime's "Dexter" was seen by 1.5 million viewers, making it the network's most-watched telecast since at least 2004 and up 7% from last season's closer (though some critics found it yawn-worthy).
