the loss of wjz-tv's abc affiliation did not sit well with westinghouse. at the time, wjz-tv had been affiliated with abc for 46 years, longer than any station that wasn't owned by the network. westinghouse sought an affiliation deal of its own, and after several months of negotiations with the other networks, westinghouse agreed to affiliate its entire television unit with cbs. under the terms of the deal, all five group w stations would carry the entire cbs schedule with no pre-emptions except for local news emergencies (as noted above, prior to this, group w stations were known for pre-empting selected programming of their affiliated networks with group w-mandated content).
