Ideas is CBC Radio's premier program of contemporary thought, with an audience of approximately 400,000 listeners.
Ideas is broadcast Monday through Friday from 9 to 10 pm and is heard throughout Canada and the northern United States on the 402 radio stations and transmitters of the Canadian Broadcasting Corporation, Canada's public broadcaster.
Ideas is eclectic in form and content. We cover social issues, culture and the arts, geopolitics, history, biography, science and technology, and the humanities. Most of our programs are documentaries in which thoughts are gathered, contexts explored, and connections made.
