la - nope, they didn't have to share CSN-Philly with Verizon. Comcast made a business decision to do so.
I just can't figure out why C* would give its network to V*, but not D* and E*.
C* uses the NFL Sunday Ticket arguement against D*, but that doesn't explain E*. Plus, the granting of license to V* seems counter-intuitive because they'll suck subscribers away from C*, right?
Honestly, right now I think it's a paradigm thing within Comcast, because it doesn't make any sense to continue.
(off topic - I love the new Verizon FIOS TV ads attacking Xfinity. Quoting: "Same old Comcast, just a new name")
I wonder if it's just bad blood between Comcast & DTV. Wouldn't surprise me, if true. At least we have Versus back. Maybe CSN Philly some day.
