There is a tradition of using public broadcasting for debate and public education in Canada. Two popular programmes on CBC radio in the 1930’s and 1940’s were the Citizens’ Forum and the Farm Radio Forum.
“Farm Forum innovations included a regional report-back system, whereby group conclusions were collected centrally and broadcast regularly across Canada, occasionally being sent to appropriate governments. In addition, discussion – leading to self-help – resulted in diverse community ‘action projects’ such as co-operatives, new forums and folk schools. Farm and community leaders claimed that the give-and-take of these discussions provided useful training for later public life. In 1952, UNESCO commissioned research into Farm Forum techniques. Its report was published in 1954, and consequently India, Ghana and France began using Canadian Farm Forum models in their programs.” —Canadian Broadcasting Corporation
Even though radio is a one-way medium, innovations such as programme guides by mail one week in advance, local discussion groups, and national feedback on individual responses kept people actively involved. Imagine a group of farmers gathering at a neighbour’s house, bringing food for a communal supper, and then discussing issues of great social relevance, like the possibility of medicare. Today, the CBC produces programmes such as Cross-Country Checkup and the Radio Noon Phone-In for similar purposes.
