It’s been a month since the Chicago Sports Network launched, and the Comcast blackout is starting to get real for increasingly frustrated fans. The revamped Bulls are a promising 3-2, the last-place Blackhawks are 10 games into what may be a long season and Comcast’s one million Chicago-area subscribers are still in the dark, staring at a blank screen that used to be NBC Sports Chicago. On the bright side, Comcast customers in the city and suburbs should begin to see an $8 credit for the programming void on their next bill, covering that portion of the regional sports fee paid in advance last month. The regional sports fee for November, however, will remain intact, despite the ongoing carriage dispute. “We are not adjusting the regional sports network fee at this time,” a Comcast spokesperson said Wednesday.
