ABC loudly announced its arrival as a competitor on Thursday, as "
Grey's Anatomy" unseated "
CSI" as the night's top show -- at least for this week -- and helped the network claim a share of the ratings crown.
CSI had dominated the 9:00 timeslot for several years and the showdown had been considered a David and Goliath showdown. The "
Grey's Anatomy" season premiere, 15.7/23, scored a rather shocking win over CBS' "CSI," 13.5/20. Of course, with those numbers there is no reason to think CSI is going anywhere anytime soon, but the loss is sure to be a sobering wake-up for CBS.
