What is World Radio Day? We’re glad you asked. It’s a day to celebrate a medium that connects us all and brings people together regardless of where, when or how they listen. February 13 was chosen as World Radio Day because it was the day United Nations radio was established in 1946. This year, for the first time ever, Canada is taking part in the celebration. Over 600 radio stations across Canada have teamed up to make our first World Radio Day really special.
