An early demonstration of radio by Lee de Forest took place in Winnipeg in April 1910, with extensive amateur and experimental interest after that date. Regularly scheduled broadcasting did not begin until the spring of 1922, when Lynn Salton established a private station with the call sign CKZC. Both Winnipeg daily newspapers developed their own radio stations in 1922, notably providing coverage of the 1922 Provincial election. However, the stations were found to be expensive to operate. In January 1923, the newspapers agreed to get out of the broadcasting business in favor of the government-owned station.
