"Lost" (9:00-10:00 p.m.)
Jumping from its lead-in by 153% and gaining young adult audience from start to finish against the second hour of Fox's expanded "Idol," self-starter "Lost" marked its 6th week in a row to emerge as Wednesday's No. 1 scripted TV show in Adults 18-49. Beating its original drama competition in the
9 o'clock hour by wide margins in Adults 18-49, ABC's "Lost" (4.3/10) topped CBS' "Criminal Minds" by 26% (3.4/8) and NBC's "Life" by 169% (1.6/4).
