I'm not sure what your point is here. My local CW, KRCW, has had a news broadcast for a few years now and it has never had a news operation. Until recently they would run an early version of the KGW (NBC affiliate) news but now they're running KOIN's (CBS) news programs. In both cases, the CW broadcast is kind of a "dress rehearsal" of the other station's news show.
There is no satellite feed involved. Before the Internet, this kind of stuff happened in my market via microwave (or in my college town, recorded from a translator).
