I admit, I watch Grey's Anatomy. I got hooked back in 2006 during the Super Bowl. Many of my friends and I got hooked that year. How could you not (maybe you are scared of blood)? They had one of the most suspenseful, intense, and what-the-hell is happening  commercials I have every seen. So I, like many people tuned into a show that I had never before seen (at the end of the season none the less) because the commercial was so good. And then I stuck with it. Here is the ad that originally caught my eye:

Pretty good right? Now we are on to season 6 and admittedly, the show was getting a bit boring. I even made the comment "they need to do something like the Code Black episode." Low and behold someone was listening to me. At the end of the season that just finished they aired the following commercial to promote the season finale. 

Another great commercial that apparently worked; the show was up 36% in viewership from the previous episode (down 10% from last season's finale). I believe the commercials alone did a good job of capturing new viewers and the numbers seem to indicate the same. As for this season's finale? I think it was one of the best episodes of Grey's yet and think it will play a part in boosting, at the very least, the first few episodes next season. We shall see.
