Renewing a television pilot immediately following its series premiere appears to be a new trend. At least for cable networks.

After Showtime's unforeseen move to green-light another season of its 2009 comedy series 'Nurse Jackie' two days following its launch, rival HBO is also taking necessary steps to capitalize off a new show.

Earlier this week, executives over at the Home Box Office decided to sign on their post-Hurricane-Katrina-themed drama 'Treme' for a second season, following the show's successful Sunday premiere, which drew more than 1.1 million viewers.

Starring Wendell Pierce of 'The Wire' and Clarke Peters, 'Treme' is set in New Orleans and follows the lives of post-Katrina residents, including lawyers and musicians.

Taking a risk to bank on the urban drama series was no pressure for programming exec. Michael Lombardo, who is accustomed to receiving high ratings from 'The Wire' and ''Treme' creator David Simon.

"This was a no-brainer for us," Lombardo explained to Variety. "We say this about ourselves, 'It's always about the ratings.' If a show is this excellent and the audience so passionate -- for us, that's enough."

Adding that the show's producers "are the most cost effective producers we do business with" and the series was "very moderately priced."

Following the debut of the 10 p.m. telecast, a later rebroadcast drew 300,000 viewers, but that figure could quadruple due to repeat airings and video on demand, according to Variety.
