Celebrity version lifts ratings, Rosie episode awaited

And just wait until Rosie gets in the hot seat.

ABC’s celebrity “Who Wants to Be a Millionaire” appears to have set a new ratings record with Tuesday’s telecast, although reliable national data from Nielsen was unavailable on Wednesday.

According to preliminary national results, Tuesday’s edition of the quizzer scored a 23.2 rating and 38 share. That’s up from the 22.5/35 for Monday, which was a season high.

The prelim figures for total viewers, though, puts Tuesday below Monday, although an adjustment is possible today by Nielsen.

Final numbers were unavailable due to a processing problem that resulted from Nielsen’s attempts to accurately measure ABC viewership levels in homes with Time Warner subscribers. When the cable company and network came to an agreement on Tuesday afternoon, Nielsen was unable to switch back to its standard methodology in time.

According to overnight shares for the top markets, New York and Los Angeles both saw jumps from Monday, when a sizable chunk of viewers in each city was unable to watch ABC programming on Time Warner cable. In Gotham, the share jumped from a 36 to a 38, while in L.A., it went from a 31 to a 34.

Monday’s episode of celebrity “Millionaire” drew nearly 36 million viewers and established many records among demos for the quizzer phenom. The program has logged its best ratings on Tuesdays and Wednesday this season, so it won’t be a surprise if Wednesday’s episode, which featured Rosie O’Donnell among others, soars to even loftier levels. Mega-”Millionaire” fan O’Donnell has been boasting on her chatshow and elsewhere of her big-money score on the program, which was taped last month.

Among the celebs who appeared Tuesday were Vanessa L. Williams and Drew Carey. The celeb version of the quizzer concludes tonight.
