ABC won with The Bachelor (5.3) and The Bachelor: After the Final Rose (5.3).
CBS was second with How I Met Your Mother (3.9), Rules of Engagement (3.4), Two and a Half Men (5.7), The Big Bang Theory (5.9), and CSI: Miami (3.4). The season premiere of Rules was up from the last new episode of Accidentally on Purpose, but will probably end up around the same.
Fox was third with a repeat of House (2.1) and 24 (2.5). The Olympics are over, but without the House lead-in, it's still suffering.
NBC was last with Chuck (2.4) and 2 episodes of Law & Order (2.0). Chuck was up 0.2 from the last time it aired. Is that enough? Probably.
