GREY'S ANATOMY (ABC)
Scheduling history: Grey's Anatomy has been one of TV's strongest shows on two different evenings, starting with two seasons on Sunday after Desperate Housewives. It really became established as a standalone hit when ABC moved it to Thursday night in the fall of 2007.
See (who saw) how it all began: Grey's Anatomy is yet another of those major hits of today that didn't start out as a huge network priority. It was a midseason replacement for legal drama Boston Legal, which had spent most of the 2004-05 season to date in the 10:00 post-Desperate Housewives slot. Boston Legal's retention of the breakout hit had been far from great, so Grey's Anatomy got a whirl on 3/27/05, when it drew 16.25 million viewers and a 7.2/18 in the demo. Retention out of Desperate Housewives was a reasonable 67% on that evening, which looks better than the two thirds that Brothers & Sisters usually holds, since Housewives had such incredible raw numbers at the time. But while the 7.2 demo looked pretty solid, here's something fairly amazing; it remained a series low until the middle of season four, for well over two and a half calendar years. The first season finale on 5/22/05 found a whooping 9.8 in the demo.
The best of times: Until the breakout performance by Undercover Boss last season, Grey's Anatomy was known as "the last show to get a long-term boost from the Super Bowl." The post-SB numbers were substantial: 37.88 million viewers and a 16.5/38 in the demo, easily the best in recent years until Boss got comparable ones in 2010 (38.65m, 16.2/38). And the long-term boost was tangible, both within season 2 and beyond. It averaged an 8.45 in its pre-Super Bowl season 2 airings and a 10.06 in those after that airing, an increase of nearly 20%, and it went from a really good retainer of the Housewives audience to something that built on the show by noticeable amounts. Then came the somewhat risky move from the Housewives lead-in on Sundays to Thursdays, a historically troublesome night for ABC. But it was another really good season, in fact the strongest average season overall in a regular timeslot. The best run during season 3 was in February 2007, when it posted four straight results with double digit demos, including an 11.6 on 2/22/07 which was the series' highest-rated telecast outside of the post-Super Bowl airing. Overall, the show broke double digits nine times, eight of which came in February; four in February 2006, four in February 2007, and the season 3 premiere in September 2006.
The worst of times: But since its heights in seasons 2 and 3, the show's trend has been consistent - consistently bad. The season 8 average was less than 40% of the season 3 average, and each season since the fourth has seen a double-digit year-to-year drop. The worst it got in season 8 was a 2.8 demo on 4/5/11, barely a fourth of the numbers it's gotten for its highest-rated regularly scheduled eps.
Then vs. now: This show never dropped below a 7.0 demo in its first three and a half seasons. It's no longer within striking distance of those numbers, but this is one of those shows that had a hell of a long way to fall, and it's still got a ways to go before we start talking about the end of Grey's Anatomy. As its fellow mid-aughts megahits House and Desperate Housewives both wrapped up their runs in spring 2012, Grey's Anatomy rose back into the mid-3's and then above 4.0, improbably making it once again TV's most formidable drama. It'll look to ride that momentum into its seventh season as the Thursday centerpiece this fall.

I think you meant to write "into its eighth season".
Sorry for not getting back to you on this! I meant it as "seventh season as the Thursday centerpiece," as in two seasons on Sunday and seven on Thursday. I can see that was rather confusingly written.
Oh, that makes sense! :-)
Wow, Grey's never peaked above Desperate Housewives. Interesting, cause I always thought Grey's was a bigger hit than Housewives.
Still, very impressive numbers, and its great that its slowed down its year-to-year drops.
