Talk about early??..the norm these days is that you see a channel ticker scrolling across the bottom of the screen warning of a pull..now we have an early agreement??
It was pretty much the consensus of the media and experts that in the Viacom and Tribune standoffs, those companies LOST big time. They lost millions in advertising dollars, and didn't get the price they wanted (or in the case of Viacom, they didn't get EPIX rolled in as well).
Companies like CBS must have seen this happening, and figured it is better to either set a realistic price, and/or negotiate early. With these kinds of disputes, subscribers will pretty much NOT switch in the first two weeks. Those two weeks however that they are black on DirecTV, the media companies WILL lose millions of dollars.
I think CBS figured out that even 1 day of no networks on CBS means they are losing money, and they have seen the writing on the wall regarding the tough negotiation stance of DirecTV.
