Explanation:
Canada and the United States share a large border, and there has been significant intermingling of cultures as a result. Because the United States is the world's center for the entertainment industry, a great deal of American pop culture has made its way north to Canada. In an effort to retain a distinct Canadian culture, the Canadian government enacted a law that 45% of all radio and television programming must be produced in Canada. To meet this goal, the government established the National Film Board (NFB), the Canadian Broadcasting Corporation (CBC), and the Canadian Radio-Television and Telecommunications Commissions (CRTC).
