Lost 's highly divisive series finale lifted ABC to an easy ratings win Sunday night, but the show's numbers no doubt fell short of expectations. The 150-minute finale averaged 13.5 million viewers and was the show's highest-rated episode in two years. However, the hype surrounding the finale didn't translate to record-setting numbers. (ABC suggests that 20.5 million unique viewers tuned in for at least six minutes throughout the episode.) Still, Lost fever carried the network. A two-hour clip show that preceded the finale drew 11.4 million viewers and Jimmy Kimmel's "Aloha to Lost" special drew 3.2 million viewers and the show's third-largest audience ever in the adults-18-to-49 demographic.
NBC took second place for the night on the shoulders of Celebrity Apprentice, which averaged 9.3 million viewers and improved 10 percent over the previous season's finale. Taking the bronze medal for the night, Fox's animated comedies' finales all took a hit from last week's episodes. A one-hour Family Guy topped the night for the network with 6.3 million, but it was down 21 percent in the demo. The Simpsons (5.7 million viewers) and The Cleveland Show (4.9 million viewers) were down 14 percent and 15 percent, respectively. CBS placed fourth, airing a Brooks and Dunn concert special (10.1 million viewers) and a CSI repeat (6.8 million viewers).
