The CW premiered new seasons of 90210 and Gossip Girl on Monday and earned some decent numbers for the fifth network. For 90210, it was the network’s best performance among adults 18-34 (1.2 rating/4 share) and total viewers (2 million) since December 2009. The show aired on Tuesdays at 8 p.m. last season. 90210’s ratings were up over its final episodes in May by 21% among women 18-34 and 31% in total viewers.

Gossip Girl built on its 90210 lead-in by 18% in women 18-34 and 18% among females 12 to 34 yet the episode only averaged 1.85 million viewers. The season opener was virtually flat with the drama’s season ending in May.

Originals on the CW aired against reruns of comedies on CBS and the finales of Bachelor Pad and Dating in the Dark on ABC. Pad was down 10% from last week among adults 18-49 and was the series’  lowest rated telecast ever, but the two-hour finale won its timeslot in viewers (5.80 million). Dating was up 8% in the 18-49 demo versus last week and averaged 3.50 million. 

NBC aired a repeat of America’s Got Talent.
