In the first 18 channels with Metrocast, we have channel 12 that is all Metrocast "stuff", NECN - ok, Fox 25 out of Boston - ok, Ch 56 Bos - ok, TBS - Atlanta - ok, and then HSN, Ch 38 and METV Bos filling out the 18, as far as single networks are concerned.
We have 2 PBS stations but they seldom have the same programming. But we have 2 NBC chs - one in Bos and one in ME. We have 3 ABC chs -one each in NH ME BOS. We have 2 CBS ch - ME and BOS. Most programming is the same, and hardly worthwhile.
Redundancy in power is a good thing, redundancy in critical controls on an airplane are good things, but redundancy in TV channels, not so much.
Unfortunately, it seems to be the nature of the beast.
