text1: How many affiliated stations does ABC currently have?
text2: Most Canadians have access to at least one U.S.-based ABC affiliate, either over-the-air (in areas located within proximity to the Canada–United States border) or through a cable, satellite or IPTV provider, although most ABC programs are subject to simultaneous substitution regulations imposed by the Canadian Radio-television and Telecommunications Commission that allow pay television providers to replace an American station's signal with the feed of a Canadian broadcaster to protect domestic programming rights and advertising revenue.
