Earlier this week it was mentioned that there was a dearth of ratings discussion. Below are the stats I pulled from sportsmediawatch.com, with updates for the UVA game.
Disclaimer: The SEC Network, CBS Sports Network, the Big Ten Network and the Pac-12 Network do not get Nielsen rated, and therefore we have no accurate data for those.

Game by Game
@ UConn: 1,080,000
@ Texas: 910,000
Vs. Houston: 1,050,000
Vs. Virginia: 1,640,000

BYU TV Stats Through 4 Games:
Total Games Televised Nationally: 4 (Tied for Most Televised)
Total Viewers: 4,680,000 (#23/115 [^9])
Average Viewers per Game: 1,170,000 (#48/115 [^2])

The Virginia ratings are heartening. Last season's Virginia game had the same start time, and this years game had over 5X the viewers (admittedly, last year's game was on ESPNU). Our viewership matched the Iowa vs. Iowa State rivalry game from the week before in the same time slot. Overall, we made strides, and hopefully the week off won't hurt any momentum.
I also compared where BYU's average viewership per game ranks in the other major conferences. If BYU was in Conference X, we would be ranked X in viewership:

P5
ACC.......#8
BIG10....#6
BIG12....#8
PAC12....#7
SEC........#11

G5
AAC.......#4
CUSA.....#4
MAC......#3
MWC.....#2
SUN......#2

The only conferences we gained ground in were the B1G and the MWC, both of who are suffering with their on the field product this year. We lost ground in the ACC, PAC and SEC.
