Fox's 24 kicked off its third season Tuesday night with 11.6 million viewers. Although the real-time drama was down slightly from last year, it still managed to lead the hour among adults 18-49 (tied with ABC's combo of According to Jim and Less Than Perfect). Ironically, the night's big winner was a lovable loser named Charlie Brown. ABC's telecast of It's the Great Pumpkin, Charlie Brown attracted 13.2 million and scored the best kids rating for a broadcast program since Fox's finale of American Idol last May. Way to go, Chuck!
