The Canadian Association of Broadcasters (CAB) said it will close its doors in June because it has reached an impasse with some of its members, news reports said Thursday. The association, which represents Canadian radio and television broadcasters, has been trying since December to find common ground between the broadcasters and cable operators who have disagreed strongly on the fee-for-carriage issue. Broadcasters CTV and Canwest Global have pushed for a fee on cable operators to support local over-the-air television. Cable carriers such as Rogers Communications Inc. and Shaw Communications own television stations that are CAB members. In 2009 the CAB went through a significant downsizing, cutting 14 staff positions and canceling its annual convention. News reports Thursday said Elmer Hildebrand, the CAB’s chairman, concluded that the organization would not be able to settle differences between the two groups. Hilderbrand said he wants to start a new association that would only represent radio broadcasters. The CAB was founded 84 years ago to represent radio broadcasters, later adding television stations to its membership.
