That year's race was cut short by rain, forcing Mutual to interrupt Queen for a Day to broadcast the finish of the rain-shortened event. Later in the day, Collins reported from victory lane. Slater was able to make it to the race, so Collins joined Slater in the booth as co-anchor. Sid Collins, who had served as a turn reporter for two years, was tentatively named his replacement. In 1950, due to an illness, Slater was expected to miss the broadcast. In the years after World War II, Mutual utilized the services of WIBC to produce the broadcast and provide additional talent. In the years prior to World War II, Mutual used the production services of WLW, and provided the signal to other Mutual stations across the country. Bill Slater was brought in as the anchor. Mutual / WIBC įrom 1939 to 1950, Mutual Broadcasting System covered the Indianapolis 500 nationwide with live segments at the start, the finish, and live periodic updates throughout the race. WIRE and WLW also reported from the race during the 1930s. CBS also covered the race in the late 1930s, with Ted Husing anchoring the coverage in 1936. Charlie Lyons was their announcer for 1939. NBC eventually returned, and continued until 1939, in some years also carrying live segments at the start. There was no radio coverage in 1932, as Speedway officials decided to allow newspapers exclusive coverage of the race. The first major coverage came in 1928 when NBC covered the final hour of the race live, with Graham McNamee as anchor.
