Newspaper Clipping, "Polio Threat Wanes: Goslin Expects Full Classrooms Monday"
By September 16, when the epidemic was officially declared at an end, KUOM had offered more than 150 hours of broadcasting, constituting one third of its program schedule, for shut-in youngsters in a period of six weeks.
The success of “School by Air” is shown not only by the many enthusiastic comments received from school administrators, teachers, parents, and children, but also by listening survey figures. Students on all grade levels in the Minneapolis schools were polled upon their return to classes. Reports from the 55 per cent of the schools which supplied data showed that 38 per cent of the elementary school children, and 9 per cent of the junior and senior high school students had listened to these programs in their homes. Such data as are available from St. Paul and other Minnesota towns indicate that these figures are a conservative statement as to the listening in all communities in KUOM’s service area.
