I have a couple of questions about carrying network news, particularly from ABC, and what the FCC rules were from...let's say...starting in the 1970's. First, back when ABC split into four networks, was only one ABC network permitted to be broadcast in each market, or was it permissible for one radio station to carry one ABC network, while another station carried another one (e.g. one major-market station carrying ABC Information, while another broadcasts ABC Contemporary)? I'm just curious about that because I know that, beginning in the 1990's when Radio Disney (an ABC music network) was launched, it was carried on one AM station in the St. Louis market, while another carried ABC Information news. Of course, I realize that's kind of a different situation, since one ABC network was news and the other music (not to mention the ABC Information radio station was licensed to St. Louis, while the Radio Disney station was licensed to Belleville, Illinois), but I was just wondering what sort of rules the FCC has had for ABC throughout the years, if any. Also, I remember working at an AM/FM in a small, unrated market (Farmington, to be more precise) and we carried ABC Information on the AM and ABC Entertainment on the FM. That was back in the 80's. So my second question is, if you had an AM/FM combo back in those days, did you have to carry different news networks on the AM and FM or would it have been permissible to broadcast the same news network on both stations (whether it was ABC, CBS, Mutual, or whoever)?
