It's not often that a network musical-variety show winds up at the top of the ratings, but CBS's Celine Dion special, That's Just the Woman in Me did just that Friday night. Nevertheless, the ratings were hardly anything for the network to boast about, as viewers -- particularly young adults -- continued to desert their television sets on Friday nights. The Dion special drew a 5.2 rating and a 9 share in the 9:00 hour, not much better than NBC's game show 1 vs. 100 did an hour hour earlier when it registered a 5.1/9. Two back-to-back episodes of NBC's Las Vegas at 9:00 p.m. and 10:00 p.m. also drew an almost identical 5.0/9 and 5.1/9 respectively. In fact, two reruns of Fox's House turned out to be the real winners of the night among adults 18-49, even though they averaged just a 4.3/8 in overall households.
