What are the 10 most Tivo'ed shows over the past 4 years ?

TiVo started compiling data in October 2007, so these numbers cover 4 seasons of TV. The live ratings are not included, this is entirely based on the TiVO recordings.






Here's the list :

1 - Grey's Anatomy (seasons 4, 5, 6 and 7).
2 - American Idol (seasons 7, 8, 9 and 10).
3 - Desperate Housewives (seasons 4, 5, 6 and 7).
4 - House (seasons 4, 5, 6 and 7).
5 - Lost (seasons 4, 5 and 6).
6 - CSI (seasons 8, 9, 10 and 11).
7 - 24 (seasons 7 and 8).
8 - Heroes (seasons 2, 3 and 4).
9 - The Office (seasons 4, 5, 6 and 7).
10 - Glee (seasons 1 and 2).

A few observations :

- 24 managing to be in the top 10 is impressive : first because the show was off the air from May 2007 to January 2009, and also because it ended in May 2010 : 24 made it at the 7th place with only 2 seasons.

- Same for Glee, the numbers of only 2 seasons are enough for it to be #10. Heroes and Lost both have the data of 3 seasons in there, while the other 6 shows all have had the numbers of 4 seasons weighing in this ranking.

- It's no surprise that the series airing in the busiest timeslots are here, especially Mondays at 9pm (Heroes/24) and Thursdays at 9pm (Grey's Anatomy/CSI/The Office).

- FOX is leading with 4 shows among the top 10 (24, House, American Idol, Glee), then it's ABC with 3 shows (Grey's Anatomy, Desperate Housewives, Lost), NBC comes next with 2 shows (Heroes, The Office) while CBS ("the most watched network") only has a single show in the top 10 (CSI) — which perhaps means people just don't care if they miss an episode of a CBS (cop)show.

- This top 10 echoes some rankings that have been made on the most downloaded shows, and we can find pretty much the same shows (with cable series such as Dexter making it in the top 10, I recall Smallville was in some of them too). And all these 10 shows were/are (very) strong on the 18-49 demo (except the post-season 1 Heroes, they all gather(ed) at least 3.0% of this key demographic on the first airing). 3 angles and pretty much the same results.
