NBC’s 90-minute finales of reality series “Deal or No Deal” and “The Apprentice” propelled the network into the No.1 spot Monday among its broadcast competitors, which ran mostly repeats.

“Deal” was the highest-rated program of the night in the adults 18 to 49 demographic, scoring a 5.5 preliminary national rating, a number that includes live-plus-same-day viewing, according to Nielsen Media Research.

The “Deal” finale, which included a $5 million prize and a video appearance by singer Celine Dion, improved NBC’s average in the time slot during the regular season by 45 percent (5.5 versus 3.8). “Deal” also grew 52 percent from its first half-hour at 8 p.m. (4.4) to its last at 9 p.m. (6.7).

“Apprentice,” the second-highest-rated program for the night, scored a 4.4 in adults 18 to 49, its highest rating for the current cycle of the series but its lowest-rated finale yet.

On The WB, the special two-hour series finale of family drama “Everwood” scored a 1.5 in adults 18 to 49.
