UPDATE, 3:14 PM: The final results are in and American Idol has adjusted up in the numbers. While the 2.6/9 rating (up from the 2.5/8 of fast nationals earlier today) is still a new all-time low for regularly scheduled show in the Fox series, the rise in viewership does offer some good news. Idol’s total viewership went up to 11.3 million in the final numbers. Unlike the indication from this morning’s fast nationals, the final number now show that the show has not hit its lowest viewership since August 2002. Today’s final numbers match the final numbers for the two-hour May 2 Idol broadcast. The highest rated and most watched show of the night earlier and still now, CBS’s Big Bang Theory went up in final numbers. The sitcom was up three tenths to a 4.9/17 from its 4.6/16 of fast nationals. That’s up 4% from last week’s finals. BBT was also up to 16.29 million viewers from the 15.69 million of preliminary numbers. While down 6% from last year’s finale in final numbers, last night’s Parks and Recreation season ender was up 23% in the finals from the week before with a 1.6/4. Hannibal, The Vampire Diaries, Grey’s Anatomy, Glee and Two And A Half Men were all adjusted up a tenth in the final numbers.

PREVIOUSLY, 9:12 AM: A full week into the May sweep, there was almost nowhere to go but up for most shows last night after the lows and the NFL Draft last Thursday. That however ended up not being the case for everyone, and especially not for American Idol (2.5/8). There wasn’t any more bickering between judges Mariah Carey and Nicki Minaj, but Idol still fell to a new regularly scheduled show low. Even though the episode pulled out all the stops on “throwback Thursday,” as Ryan Seacrest called it, Idol still was down more than the previous all-time adults 18-49 low of last week. The show dipped 7% from April 25’s fast nationals and 11% from last week’s final numbers. Fox’s long-running competition series slipped 4% in viewership from last week to 11.0 million, the lowest viewership the series has seen since August 7, 2002 — during its first season. Following Idol, a a Stevie Wonder-themed Glee (1.8/5) was even with last week.

The Big Bang Theory (4.6/16) was the most-watched and highest-rated show last night, though it bopped up a mere 2% from last week. Rising from April 25’s series low, Two And A Half Men (3.1/10) was up 11% from last week. That was not the case for the rest of CBS’ night; Person Of Interest (2.4/7) and Elementary (2.0/6) were both even with last week’s airings. That left the former tied for a series low and the freshman latter tied for a season low. CBS won the night in total viewers (12.02 million) and adults 18-49.

On ABC the night started with the season finale of Wife Swap (1.1/4), which was flat with last week’s show but up 10% from its previous season finale on August 8, 2010. Last week, Grey’s Anatomy (2.9/8) was down 7% from its previous original. Last night the medical drama was up by the same amount from the April 25 airing. The only show to actually go up last week, Scandal (2.6/8), saw a stumble last night, dipping 7% from its April 25 show. A strong ratings deliverer this year for ABC, Scandal has beaten Idol in the key demo in fast nationals the past two weeks and ended up tied with the Fox series in final numbers last week. The political thriller wraps up its second season May 16.

On NBC, Community (1.2/4) was up 20% from its series-low tie April 25. With two weeks to go before its series finale, last night’s hourlong episode of The Office (1.8/6) was up 6% from last week’s half hour.  Parks And Recreation (1.5/4) had its Season 5 finale Thursday, with the comedy up 15% from its April 25 show but down 12% from its last finale on May 10, 2012. Freshman Hannibal (1.0/3) was muted last night. The Silence Of The Lambs prequel was even with its April 25 airing to tie a season low.

The CW’s The Vampire Diaries (0.9/3) was down 10% from last week’s show, which introduced the network’s new spinoff The Originals. Beauty And The Beast (0.5/1) was even with its April 25 episode.
