ABC looks like it has another drama hit on its hands. “Grey’s Anatomy” held up extremely well in its second outing Sunday behind another highly rated installment of Desperate Housewives. Grey’s Anatomy pulled in an impressive 18.2 million viewers and 7.9 rating/19 share in the adults 18-49 demographic, coming out of 24.4 million viewers and 10.7/24 for “Housewives” in the 9 p.m. hour, according to preliminary estimates from Nielsen Media Research. “Anatomy” crushed the competition from a repeat of NBC’s Crossing Jordan (9.5 million, 2.7/7) and the final hour of CBS telecast of the 2002 Denzel Washington starrer John Q, which averaged 7.6 million viewers and 2.2/5 in adults 18-49.- Reuters/The Hollywood Reporter
