The cable + sports networks have people in a headlock, though. Want to sign up for Big 10 football? You must have Comcast. A lot of other sports networks are similar. The minute sports goes to an a la carte or subscription model that doesn't require a cable package, I think it will signal the death knell for big cable.
Right now, the comcast packages look like this:
1. Internet only ~$50/month
2. Internet + really basic cable ~$50/month (for me it was actually less to have both, they made me get a cable box to get $10 less, it makes no sense except for the fact that they want to up sell me later.
3. Internet plus sports ~$100/month (plus you get lots of other garbage)
4. Internet plus HBO ~$100/month (plus you get lots of other garbage)
5. Internet plus HBO plus sports ~$110/month
6. Internet plus everything including a phone $180/month
Sports and/or HBO are about half the revenue which is exactly why the cable companies want to make them bundled.
The only way out I can think of to get out of this bundling is to legislate no exclusivity for content, or at least live content. That would be major blow to the revenue streams of college teams & the NFL.
