Over at NBC, there is problems aplenty beginning with Chuck, which is not strong enough to anchor Monday at just a fourth-place finish in both total viewers (5.35 million) and adults 18-49 (1.9/ 5) at 8 p.m. Without the necessary lead-in support, week four of The Event lost more steam, with 6.45 million viewers (#3) and a 2.2/ 5 in the demo (#2) from 9-10 p.m. In just three weeks, The Event has dipped by a hefty 4.43 million viewers and 39 percent among adults 18-49 from its debut on Sept. 20. Although The Event avoids the listing of losers for still building by double-digits from Chuck, more erosion next week will be unforgivable. At 10 p.m., week four of lead-out Chase finished a distant third with a series-low 5.00 million viewers and a 1.5/ 4 among adults 18-49.
