Prospects look good for a second season of the Sarah Connor Chronicles.
On Friday, March 7, Kristin Dos Santos reported that "barring any
apocalyptic shifts at the Fox network, Terminator is very likely to
return in the fall."
At the time, I tried to take that with a grain of salt, as it was based
on a conversation with star Thomas Dekker at an American Idol party.
But that grain gained some momentum, as Yahoo.news posted a more
general article on the probable fate of shows on the bubble.
The article posted the following,
"'Terminator: The Sarah Connor Chronicles. Fans need not worry: Sources
say that "Terminator" will be back. Fox executives like the creative
product and thought the finale's performance last week was solid. The
network also spent a considerable amount marketing the show, giving
Season 2 some cost benefit. Also: The fourth "Terminator" movie comes
out in 2009, and as "The Simpsons Movie" proved, there are promotional
advantages to film-TV synergy."
Various pundits watching the show’s middle of the road performance over
its truncated nine episode season have pointed out the show's success
on DVR and iTunes. Presumably good iTunes sales herald hot DVD sales
down the road. While Sarah Connor is produced by Warner Bros, and
therefore Warner, not Fox will benefit from DVD sales, this may mean
that Warner execs will be more willing to negotiate a reduced price on
a 2nd season with the expectation of DVD gold down the road.
However, since Fox doesn't generally announce those show renewal until
their upfronts in May, that may mean a long wait for fans.
In the meantime, just to give the timeshifting/DVR numbers some relevance, and because charts are fun,
here's what the +7 day DVR lift looks like in a chart based on numbers
from tvbythenumbers.com. Figures up to 1.6 (Dungeons and Dragons).

Episode's relative rank in time shift increase
1.1 (Pilot): 6
1.2 (Gnothi Seauton): 4
1.3 (Turk): 5
1.4 (Heavy Metal): 6
1.5 (Queens Gambit): 5
1.6 (Dungeons & Dragons): 7
