An NBA assist to TNT, TBS

Lifetime No.1-rated network overall in households

NEW YORK — The National Basketball Assn. Playoffs performed their usual annual magic on the ratings of TBS and TNT, which wound up in the No. 1 and No. 2 slots among all ad-supported networks in adults 18 to 34 and adults 18 to 49 for the week ended May 19.

But the No.1-rated network overall in households was Lifetime, which averaged a 2.0 primetime rating for the week, edging out Nickelodeon/Nick at Nite, which finished with an unusually lofty 1.9 rating in cable homes, helped dramatically by two half-hour “SpongeBob SquarePants” episodes on May 17 at 9. The 9:30 “SpongeBob” ended up the highest-rated program in basic cable for the week, averaging a 4.5 rating in cable homes. The 9-p.m. “SpongeBob” lead-in scored a 4.2 rating, good for No. 2 over all.

The highest-rated basketball game of the week was the May 14 San Antonio Spurs-Los Angeles Lakers contest on TBS, which averaged a 3.9 rating in cable homes over two hours and 45 minutes.

The second-highest-rated game was the one pitting the Philadelphia 76ers against the Boston Celtics on TNT May 13, which averaged a 3.5 rating from 8:58 p.m. to 11:45 p.m.

The big audience for the games was the primary reason TNT and TBS finished in a tie for third place in primetime with Cartoon, all averaging a 1.6 rating in cable homes.

And for Ozzy watchers: In its first week as a rerun series, MTV’s “The Osbournes” on May 14 fell from its stratospheric perch at the top, landing out of the top 50 for the first time since its premiere 10 weeks ago.

But MTV looked on the bright side: Ozzy and his family, even in repeats, wound up in fourth place for the week among adults 18 to 34 and in eighth place among adults 18 to 49.
