As others have remembered, Big 10 Network was offered to all subscribers for a short while as a free preview. After some date (as I recall, the start of football season), the availability of it changed. Since I'm in the Big 10's region, I wasn't impacted like people outside of it are. Basically, people in this region kept it, but it also sounds like you had to have a package level or higher (I have had either AT200 or AT250 for quite a while).
