Fox was the 1st one that started doing this back in the summer of 2010 and ESPN followed in January 2011. Fox has all of their content in widescreen only now. I think NBC does widescreen only on NBCSN as I thought they were still doing center-cut on NBC the network (I'll have to check the Kings/Rangers game tonight to see). CBS went widescreen on sports last summer and I'm hoping they'll go widescreen on their news and entertainment programming by the time the new fall season starts although we'll have to wait and see. ABC is in a weird situation being that they're owned by Disney and show ESPN on ABC. You would think that since ESPN is widescreen only now and that ABC's biggest affiliation group, Scripps, has all their stations in widescreen only now (regardless of affiliation) that the whole network would go widescreen on all of their content by now, but that's not the case. I don't get what's holding ABC, CBS, and NBC from going widescreen only 24/7 as the only 2 shows on those 3 networks that are SD only are Let's make a deal and Big Brother, both on CBS. CBS can easily flip LMAD to HD but they choose not to. Big brother I understand may be harder to do but even so, CBS can afford to do it.
