'Dexter' season finale slashes records

Was Showtime's most-watched original series episode

The fourth-season finale of Showtime's "Dexter" was seen by 2.6 million viewers -- blowing away all modern records for the network.

The brutal "Dexter" closer was the most-watched original series episode ever on the network, and the most watched telecast since a Mike Tyson fight in 1999. "Dexter" was 54% higher than last year's finale.

The season three finale of "Californication" was also a series high, 1.1 million viewers, though still dropping considerably from its lead in.
