Note this is for BYU's bye weekend. The guy who posts these numbers each week didn't post the CFB numbers last week as he was traveling to the LSU/Alabama game but he did include them this week when he reported on week 11 numbers so I'll be posting those in a few minutes.

Below are the number of times each team has appeared nationally on a channel that has enough distribution and a high enough event rating that Nielsen tracks/reports on it.
