Lakisha Jones wasn't the only one who departed from American Idol Wednesday night. So did nearly nearly four and a half million viewers compared with audience figures for the comparable broadcast a year ago. According to Nielsen data, Idol drew 24.49 million viewers versus 28.85 million last year. Nevertheless, the show continued to whip the competition as it posted a 17.0 rating and a 26 share in the 9:00 p.m. hour. Fox's lead-in show, Bones, also performed strongly, scoring a 7.4 rating and a 12 share at 8:00, well ahead of the series finale of CBS's Jericho, which posted a 5.0/8. CBS took over first place at 10:00, however, with CSI: NY posting a 9.0/14, just ahead of ABC's Lost's 8.0/13.
