The largely unregulated early years of Canadian radio were vital to development of broadcasting policy. The Report of the Royal Commission on Radio Broadcasting in 1929 and American broadcasting both changed the direction of Canadian broadcasting, but were mitigated by the early, largely unregulated years. Broadcasters operated initially as small, independent, and local broadcasters, then, national networks developed in stages during the 1920s and 1930s. The late adoption of radio broadcasting policy to build a national network in Canada allowed other practices to take root in the wake of other examples, in particular, American commercial broadcasting. By 1929 when the Aird Report recommended a national network, the potential impact of the report was shaped by the path of early broadcasting and the shifts forced on Canada by American broadcasting and policy. Eventually Canada forged its own course that pulled in both directions, permitting both private commercial networks and public national networks.
