The WB has renewed teen drama One Tree Hill for a second season in 2004-05.

The series, starring Chad Michael Murray, got off to a modest start with just 2.5 million viewers in the adults 18-34 demo but has steadily risen across the season to 4.4 million.

The show has also performed particularly well in the women 18-34 and female teen demos, becoming the second highest-rated drama in female teens to FOX's The O.C.

"One Tree Hill became the story of the year for us this season," said Jordan Levin, WB co-CEO. "One Tree Hill was originally developed as a midseason program and thus did not benefit from the traditional launch support. Once the marketing and PR campaigns hit at mid-season, the show found its creative footing and what ensued was a show that was strong enough to win its timeslot in key demos.

"Chad Michael Murray, in whom we have had tremendous faith for years, has emerged as one of the hottest young actors in our business and leads what we think of as a breakout ensemble cast."
