well I don't know how I did it but I found this:
Xfinity TV customers who live within the Pac-12 geographical footprint will receive a network tailored to their regions as well as nationally televised live events. Customers who reside outside the Pac-12 region will need to subscribe to the Sports Entertainment Package for access. In addition, Xfinity TV customers may watch Pac-12 Network content online (live streaming of games) inside and outside of their homes on any digital device, including computers, smartphones and tablets.
So this is where they make their money
Hmmm..maybe I should become a Gopher fan hahah
EDIT: Thought right now it looks like the SEP is only 5.00 a month for the first 6 months then goes up to 7.95. I think thats a pretty good deal
